# @overload initialize(options)
    #   @param [Hash] options
    #   @option options [required, Aws::CredentialProvider] :credentials
    #     Your AWS credentials. This can be an instance of any one of the
    #     following classes:
    #
    #     * `Aws::Credentials` - Used for configuring static, non-refreshing
    #       credentials.
    #
    #     * `Aws::InstanceProfileCredentials` - Used for loading credentials
    #       from an EC2 IMDS on an EC2 instance.
    #
    #     * `Aws::SharedCredentials` - Used for loading credentials from a
    #       shared file, such as `~/.aws/config`.
    #
    #     * `Aws::AssumeRoleCredentials` - Used when you need to assume a role.
    #
    #     When `:credentials` are not configured directly, the following
    #     locations will be searched for credentials:
    #
    #     * `Aws.config[:credentials]`
    #     * The `:access_key_id`, `:secret_access_key`, and `:session_token` options.
    #     * ENV['AWS_ACCESS_KEY_ID'], ENV['AWS_SECRET_ACCESS_KEY']
    #     * `~/.aws/credentials`
    #     * `~/.aws/config`
    #     * EC2 IMDS instance profile - When used by default, the timeouts are
    #       very aggressive. Construct and pass an instance of
    #       `Aws::InstanceProfileCredentails` to enable retries and extended
    #       timeouts.
    #

# @!group API Operations

# Returns a set of temporary security credentials that you can use to
    # access AWS resources that you might not normally have access to. These
    # temporary credentials consist of an access key ID, a secret access
    # key, and a security token. Typically, you use `AssumeRole` within your
    # account or for cross-account access. For a comparison of `AssumeRole`
    # with other API operations that produce temporary credentials, see
    # [Requesting Temporary Security Credentials][1] and [Comparing the AWS
    # STS API operations][2] in the *IAM User Guide*.
    #
    # You cannot use AWS account root user credentials to call `AssumeRole`.
    # You must use credentials for an IAM user or an IAM role to call
    # `AssumeRole`.
    #
    # For cross-account access, imagine that you own multiple accounts and
    # need to access resources in each account. You could create long-term
    # credentials in each account to access those resources. However,
    # managing all those credentials and remembering which one can access
    # which account can be time consuming. Instead, you can create one set
    # of long-term credentials in one account. Then use temporary security
    # credentials to access all the other accounts by assuming roles in
    # those accounts. For more information about roles, see [IAM Roles][3]
    # in the *IAM User Guide*.
    #
    # By default, the temporary security credentials created by `AssumeRole`
    # last for one hour. However, you can use the optional `DurationSeconds`
    # parameter to specify the duration of your session. You can provide a
    # value from 900 seconds (15 minutes) up to the maximum session duration
    # setting for the role. This setting can have a value from 1 hour to 12
    # hours. To learn how to view the maximum value for your role, see [View
    # the Maximum Session Duration Setting for a Role][4] in the *IAM User
    # Guide*. The maximum session duration limit applies when you use the
    # `AssumeRole*` API operations or the `assume-role*` CLI commands.
    # However the limit does not apply when you use those operations to
    # create a console URL. For more information, see [Using IAM Roles][5]
    # in the *IAM User Guide*.
    #
    # The temporary security credentials created by `AssumeRole` can be used
    # to make API calls to any AWS service with the following exception: You
    # cannot call the AWS STS `GetFederationToken` or `GetSessionToken` API
    # operations.
    #
    # (Optional) You can pass inline or managed [session policies][6] to
    # this operation. You can pass a single JSON policy document to use as
    # an inline session policy. You can also specify up to 10 managed
    # policies to use as managed session policies. The plain text that you
    # use for both inline and managed session policies shouldn't exceed
    # 2048 characters. Passing policies to this operation returns new
    # temporary credentials. The resulting session's permissions are the
    # intersection of the role's identity-based policy and the session
    # policies. You can use the role's temporary credentials in subsequent
    # AWS API calls to access resources in the account that owns the role.
    # You cannot use session policies to grant more permissions than those
    # allowed by the identity-based policy of the role that is being
    # assumed. For more information, see [Session Policies][6] in the *IAM
    # User Guide*.
    #
    # To assume a role from a different account, your AWS account must be
    # trusted by the role. The trust relationship is defined in the role's
    # trust policy when the role is created. That trust policy states which
    # accounts are allowed to delegate that access to users in the account.
    #
    # A user who wants to access a role in a different account must also
    # have permissions that are delegated from the user account
    # administrator. The administrator must attach a policy that allows the
    # user to call `AssumeRole` for the ARN of the role in the other
    # account. If the user is in the same account as the role, then you can
    # do either of the following:
    #
    # * Attach a policy to the user (identical to the previous user in a
    #   different account).
    #
    # * Add the user as a principal directly in the role's trust policy.
    #
    # In this case, the trust policy acts as an IAM resource-based policy.
    # Users in the same account as the role do not need explicit permission
    # to assume the role. For more information about trust policies and
    # resource-based policies, see [IAM Policies][7] in the *IAM User
    # Guide*.
    #
    # **Using MFA with AssumeRole**
    #
    # (Optional) You can include multi-factor authentication (MFA)
    # information when you call `AssumeRole`. This is useful for
    # cross-account scenarios to ensure that the user that assumes the role
    # has been authenticated with an AWS MFA device. In that scenario, the
    # trust policy of the role being assumed includes a condition that tests
    # for MFA authentication. If the caller does not include valid MFA
    # information, the request to assume the role is denied. The condition
    # in a trust policy that tests for MFA authentication might look like
    # the following example.
    #
    # `"Condition": \{"Bool": \{"aws:MultiFactorAuthPresent": true\}\}`
    #
    # For more information, see [Configuring MFA-Protected API Access][8] in
    # the *IAM User Guide* guide.
    #
    # To use MFA with `AssumeRole`, you pass values for the `SerialNumber`
    # and `TokenCode` parameters. The `SerialNumber` value identifies the
    # user's hardware or virtual MFA device. The `TokenCode` is the
    # time-based one-time password (TOTP) that the MFA device produces.

    #
    # @option params [required, String] :role_session_name
    #   An identifier for the assumed role session.
    #
    #   Use the role session name to uniquely identify a session when the same
    #   role is assumed by different principals or for different reasons. In
    #   cross-account scenarios, the role session name is visible to, and can
    #   be logged by the account that owns the role. The role session name is
    #   also used in the ARN of the assumed role principal. This means that
    #   subsequent cross-account API requests that use the temporary security
    #   credentials will expose the role session name to the external account
    #   in their AWS CloudTrail logs.
    #
    #   The regex used to validate this parameter is a string of characters
    #   consisting of upper- and lower-case alphanumeric characters with no

    #
    #   This parameter is optional. You can provide up to 10 managed policy
    #   ARNs. However, the plain text that you use for both inline and managed
    #   session policies shouldn't exceed 2048 characters. For more
    #   information about ARNs, see [Amazon Resource Names (ARNs) and AWS
    #   Service Namespaces][1] in the AWS General Reference.

    #   from 900 seconds (15 minutes) up to the maximum session duration
    #   setting for the role. This setting can have a value from 1 hour to 12
    #   hours. If you specify a value higher than this setting, the operation
    #   fails. For example, if you specify a session duration of 12 hours, but

    # @option params [String] :external_id
    #   A unique identifier that might be required when you assume a role in
    #   another account. If the administrator of the account to which the role
    #   belongs provided you with an external ID, then provide that value in
    #   the `ExternalId` parameter. This value can be any string, such as a
    #   passphrase or account number. A cross-account role is usually set up
    #   to trust everyone in an account. Therefore, the administrator of the
    #   trusting account might send an external ID to the administrator of the
    #   trusted account. That way, only someone with the ID can assume the
    #   role, rather than everyone in the account. For more information about
    #   the external ID, see [How to Use an External ID When Granting Access

# Returns a set of temporary security credentials for users who have
    # been authenticated via a SAML authentication response. This operation
    # provides a mechanism for tying an enterprise identity store or

    # or configuration. For a comparison of `AssumeRoleWithSAML` with the
    # other API operations that produce temporary credentials, see
    # [Requesting Temporary Security Credentials][1] and [Comparing the AWS
    # STS API operations][2] in the *IAM User Guide*.
    #
    # The temporary security credentials returned by this operation consist
    # of an access key ID, a secret access key, and a security token.
    # Applications can use these temporary security credentials to sign
    # calls to AWS services.
    #
    # By default, the temporary security credentials created by
    # `AssumeRoleWithSAML` last for one hour. However, you can use the
    # optional `DurationSeconds` parameter to specify the duration of your
    # session. Your role session lasts for the duration that you specify, or
    # until the time specified in the SAML authentication response's
    # `SessionNotOnOrAfter` value, whichever is shorter. You can provide a
    # `DurationSeconds` value from 900 seconds (15 minutes) up to the
    # maximum session duration setting for the role. This setting can have a
    # value from 1 hour to 12 hours. To learn how to view the maximum value
    # for your role, see [View the Maximum Session Duration Setting for a
    # Role][3] in the *IAM User Guide*. The maximum session duration limit
    # applies when you use the `AssumeRole*` API operations or the
    # `assume-role*` CLI commands. However the limit does not apply when you
    # use those operations to create a console URL. For more information,
    # see [Using IAM Roles][4] in the *IAM User Guide*.
    #
    # The temporary security credentials created by `AssumeRoleWithSAML` can
    # be used to make API calls to any AWS service with the following
    # exception: you cannot call the STS `GetFederationToken` or
    # `GetSessionToken` API operations.
    #
    # (Optional) You can pass inline or managed [session policies][5] to
    # this operation. You can pass a single JSON policy document to use as
    # an inline session policy. You can also specify up to 10 managed
    # policies to use as managed session policies. The plain text that you
    # use for both inline and managed session policies shouldn't exceed
    # 2048 characters. Passing policies to this operation returns new
    # temporary credentials. The resulting session's permissions are the
    # intersection of the role's identity-based policy and the session
    # policies. You can use the role's temporary credentials in subsequent
    # AWS API calls to access resources in the account that owns the role.
    # You cannot use session policies to grant more permissions than those
    # allowed by the identity-based policy of the role that is being
    # assumed. For more information, see [Session Policies][5] in the *IAM
    # User Guide*.
    #
    # Before your application can call `AssumeRoleWithSAML`, you must
    # configure your SAML identity provider (IdP) to issue the claims
    # required by AWS. Additionally, you must use AWS Identity and Access
    # Management (IAM) to create a SAML provider entity in your AWS account
    # that represents your identity provider. You must also create an IAM
    # role that specifies this SAML provider in its trust policy.
    #
    # Calling `AssumeRoleWithSAML` does not require the use of AWS security
    # credentials. The identity of the caller is validated by using keys in
    # the metadata document that is uploaded for the SAML provider entity
    # for your identity provider.
    #
    # Calling `AssumeRoleWithSAML` can result in an entry in your AWS
    # CloudTrail logs. The entry includes the value in the `NameID` element
    # of the SAML assertion. We recommend that you use a `NameIDType` that
    # is not associated with any personally identifiable information (PII).
    # For example, you could instead use the Persistent Identifier
    # (`urn:oasis:names:tc:SAML:2.0:nameid-format:persistent`).

    # have a value from 1 hour to 12 hours. To learn how to view the maximum
    # value for your role, see [View the Maximum Session Duration Setting
    # for a Role][7] in the *IAM User Guide*. The maximum session duration
    # limit applies when you use the `AssumeRole*` API operations or the
    # `assume-role*` CLI commands. However the limit does not apply when you
    # use those operations to create a console URL. For more information,
    # see [Using IAM Roles][8] in the *IAM User Guide*.
    #
    # The temporary security credentials created by
    # `AssumeRoleWithWebIdentity` can be used to make API calls to any AWS
    # service with the following exception: you cannot call the STS
    # `GetFederationToken` or `GetSessionToken` API operations.
    #
    # (Optional) You can pass inline or managed [session policies][9] to
    # this operation. You can pass a single JSON policy document to use as
    # an inline session policy. You can also specify up to 10 managed
    # policies to use as managed session policies. The plain text that you
    # use for both inline and managed session policies shouldn't exceed
    # 2048 characters. Passing policies to this operation returns new
    # temporary credentials. The resulting session's permissions are the
    # intersection of the role's identity-based policy and the session
    # policies. You can use the role's temporary credentials in subsequent
    # AWS API calls to access resources in the account that owns the role.
    # You cannot use session policies to grant more permissions than those
    # allowed by the identity-based policy of the role that is being
    # assumed. For more information, see [Session Policies][9] in the *IAM
    # User Guide*.
    #
    # Before your application can call `AssumeRoleWithWebIdentity`, you must
    # have an identity token from a supported identity provider and create a
    # role that the application can assume. The role that your application
    # assumes must trust the identity provider that is associated with the
    # identity token. In other words, the identity provider must be
    # specified in the role's trust policy.
    #
    # Calling `AssumeRoleWithWebIdentity` can result in an entry in your AWS
    # CloudTrail logs. The entry includes the [Subject][10] of the provided
    # Web Identity Token. We recommend that you avoid using any personally
    # identifiable information (PII) in this field. For example, you could
    # instead use a GUID or a pairwise identifier, as [suggested in the OIDC
    # specification][11].

    #
    # @option params [required, String] :web_identity_token
    #   The OAuth 2.0 access token or OpenID Connect ID token that is provided

# Returns a set of temporary security credentials (consisting of an
    # access key ID, a secret access key, and a security token) for a
    # federated user. A typical use is in a proxy application that gets
    # temporary security credentials on behalf of distributed applications
    # inside a corporate network. You must call the `GetFederationToken`
    # operation using the long-term security credentials of an IAM user. As
    # a result, this call is appropriate in contexts where those credentials
    # can be safely stored, usually in a server-based application. For a
    # comparison of `GetFederationToken` with the other API operations that
    # produce temporary credentials, see [Requesting Temporary Security
    # Credentials][1] and [Comparing the AWS STS API operations][2] in the
    # *IAM User Guide*.
    #
    # <note markdown="1"> You can create a mobile-based or browser-based app that can
    # authenticate users using a web identity provider like Login with
    # Amazon, Facebook, Google, or an OpenID Connect-compatible identity
    # provider. In this case, we recommend that you use [Amazon Cognito][3]
    # or `AssumeRoleWithWebIdentity`. For more information, see [Federation
    # Through a Web-based Identity Provider][4].
    #
    #  </note>
    #
    # You can also call `GetFederationToken` using the security credentials
    # of an AWS account root user, but we do not recommend it. Instead, we
    # recommend that you create an IAM user for the purpose of the proxy
    # application. Then attach a policy to the IAM user that limits
    # federated users to only the actions and resources that they need to
    # access. For more information, see [IAM Best Practices][5] in the *IAM
    # User Guide*.
    #
    # The temporary credentials are valid for the specified duration, from
    # 900 seconds (15 minutes) up to a maximum of 129,600 seconds (36
    # hours). The default is 43,200 seconds (12 hours). Temporary
    # credentials that are obtained by using AWS account root user
    # credentials have a maximum duration of 3,600 seconds (1 hour).
    #
    # The temporary security credentials created by `GetFederationToken` can
    # be used to make API calls to any AWS service with the following
    # exceptions:
    #
    # * You cannot use these credentials to call any IAM API operations.
    #
    # * You cannot call any STS API operations except `GetCallerIdentity`.
    #
    # **Permissions**
    #
    # You must pass an inline or managed [session policy][6] to this
    # operation. You can pass a single JSON policy document to use as an
    # inline session policy. You can also specify up to 10 managed policies
    # to use as managed session policies. The plain text that you use for
    # both inline and managed session policies shouldn't exceed 2048
    # characters.
    #
    # Though the session policy parameters are optional, if you do not pass
    # a policy, then the resulting federated user session has no
    # permissions. The only exception is when the credentials are used to
    # access a resource that has a resource-based policy that specifically
    # references the federated user session in the `Principal` element of
    # the policy. When you pass session policies, the session permissions
    # are the intersection of the IAM user policies and the session policies
    # that you pass. This gives you a way to further restrict the
    # permissions for a federated user. You cannot use session policies to
    # grant more permissions than those that are defined in the permissions
    # policy of the IAM user. For more information, see [Session
    # Policies][6] in the *IAM User Guide*. For information about using
    # `GetFederationToken` to create temporary security credentials, see

# Returns a set of temporary credentials for an AWS account or IAM user.
    # The credentials consist of an access key ID, a secret access key, and
    # a security token. Typically, you use `GetSessionToken` if you want to
    # use MFA to protect programmatic calls to specific AWS API operations
    # like Amazon EC2 `StopInstances`. MFA-enabled IAM users would need to
    # call `GetSessionToken` and submit an MFA code that is associated with
    # their MFA device. Using the temporary security credentials that are
    # returned from the call, IAM users can then make programmatic calls to
    # API operations that require MFA authentication. If you do not supply a
    # correct MFA code, then the API returns an access denied error. For a
    # comparison of `GetSessionToken` with the other API operations that
    # produce temporary credentials, see [Requesting Temporary Security
    # Credentials][1] and [Comparing the AWS STS API operations][2] in the
    # *IAM User Guide*.
    #
    # The `GetSessionToken` operation must be called by using the long-term
    # AWS security credentials of the AWS account root user or an IAM user.
    # Credentials that are created by IAM users are valid for the duration
    # that you specify. This duration can range from 900 seconds (15
    # minutes) up to a maximum of 129,600 seconds (36 hours), with a default
    # of 43,200 seconds (12 hours). Credentials based on account credentials
    # can range from 900 seconds (15 minutes) up to 3,600 seconds (1 hour),
    # with a default of 1 hour.
    #
    # The temporary security credentials created by `GetSessionToken` can be
    # used to make API calls to any AWS service with the following
    # exceptions:
    #
    # * You cannot call any IAM API operations unless MFA authentication
    #   information is included in the request.
    #
    # * You cannot call any STS API *except* `AssumeRole` or
    #   `GetCallerIdentity`.
    #
    # <note markdown="1"> We recommend that you do not call `GetSessionToken` with AWS account
    # root user credentials. Instead, follow our [best practices][3] by
    # creating one or more IAM users, giving them the necessary permissions,
    # and using IAM users for everyday interaction with AWS.
    #
    #  </note>
    #
    # The credentials that are returned by `GetSessionToken` are based on
    # permissions associated with the user whose credentials were used to
    # call the operation. If `GetSessionToken` is called using AWS account
    # root user credentials, the temporary credentials have root user
    # permissions. Similarly, if `GetSessionToken` is called using the
    # credentials of an IAM user, the temporary credentials have the same
    # permissions as the IAM user.
