// AssumeRole API operation for AWS Security Token Service.
//
// 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 (https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_request.html)
// and Comparing the AWS STS API operations (https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_request.html#stsapi_comparison)
// 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 (https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles.html)
// in the IAM User Guide.
//
// Session Duration
//
// 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 (https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_use.html#id_roles_use_view-role-max-session)
// 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 (https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_use.html)
// in the IAM User Guide.
//
// Permissions
//
// 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 (https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies.html#policies_session)
// 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 can't exceed 2,048 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 (https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies.html#policies_session)
// 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 (https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies.html)
// in the IAM User Guide.
//
// Tags
//
// (Optional) You can pass tag key-value pairs to your session. These tags are
// called session tags. For more information about session tags, see Passing
// Session Tags in STS (https://docs.aws.amazon.com/IAM/latest/UserGuide/id_session-tags.html)
// in the IAM User Guide.
//
// An administrator must grant you the permissions necessary to pass session
// tags. The administrator can also create granular permissions to allow you
// to pass only specific session tags. For more information, see Tutorial: Using
// Tags for Attribute-Based Access Control (https://docs.aws.amazon.com/IAM/latest/UserGuide/tutorial_attribute-based-access-control.html)
// in the IAM User Guide.
//
// You can set the session tags as transitive. Transitive tags persist during
// role chaining. For more information, see Chaining Roles with Session Tags
// (https://docs.aws.amazon.com/IAM/latest/UserGuide/id_session-tags.html#id_session-tags_role-chaining)
// 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 (https://docs.aws.amazon.com/IAM/latest/UserGuide/MFAProtectedAPI.html)
// 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.
//
// Returns awserr.Error for service API and SDK errors. Use runtime type assertions
// with awserr.Error's Code and Message methods to get detailed information about
// the error.
//
// See the AWS API reference guide for AWS Security Token Service's
// API operation AssumeRole for usage and error information.
//
// Returned Error Codes:
//   * ErrCodeMalformedPolicyDocumentException "MalformedPolicyDocument"
//   The request was rejected because the policy document was malformed. The error
//   message describes the specific error.
//
//   * ErrCodePackedPolicyTooLargeException "PackedPolicyTooLarge"
//   The request was rejected because the total packed size of the session policies
//   and session tags combined was too large. An AWS conversion compresses the
//   session policy document, session policy ARNs, and session tags into a packed
//   binary format that has a separate limit. The error message indicates by percentage
//   how close the policies and tags are to the upper size limit. For more information,
//   see Passing Session Tags in STS (https://docs.aws.amazon.com/IAM/latest/UserGuide/id_session-tags.html)
//   in the IAM User Guide.
//
//   You could receive this error even though you meet other defined session policy
//   and session tag limits. For more information, see IAM and STS Entity Character
//   Limits (https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_enable-regions.html)
//   in the IAM User Guide.
//
//   * ErrCodeRegionDisabledException "RegionDisabledException"

//
// Permissions
//
// 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 (https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies.html#policies_session)
// 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 can't exceed 2,048 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 (https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies.html#policies_session)
// in the IAM User Guide.
//
// Tags
//
// (Optional) You can configure your IdP to pass attributes into your web identity
// token as session tags. Each session tag consists of a key name and an associated
// value. For more information about session tags, see Passing Session Tags
// in STS (https://docs.aws.amazon.com/IAM/latest/UserGuide/id_session-tags.html)
// in the IAM User Guide.
//
// You can pass up to 50 session tags. The plain text session tag keys can’t
// exceed 128 characters and the values can’t exceed 256 characters. For these
// and additional limits, see IAM and STS Character Limits (https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_iam-limits.html#reference_iam-limits-entity-length)
// in the IAM User Guide.
//
// An AWS conversion compresses the passed session policies and session tags
// into a packed binary format that has a separate limit. Your request can fail
// for this limit even if your plain text meets the other requirements. The
// PackedPolicySize response element indicates by percentage how close the policies
// and tags for your request are to the upper size limit.
//
// You can pass a session tag with the same key as a tag that is attached to
// the role. When you do, the session tag overrides the role tag with the same
// key.
//
// An administrator must grant you the permissions necessary to pass session
// tags. The administrator can also create granular permissions to allow you
// to pass only specific session tags. For more information, see Tutorial: Using
// Tags for Attribute-Based Access Control (https://docs.aws.amazon.com/IAM/latest/UserGuide/tutorial_attribute-based-access-control.html)
// in the IAM User Guide.
//
// You can set the session tags as transitive. Transitive tags persist during
// role chaining. For more information, see Chaining Roles with Session Tags
// (https://docs.aws.amazon.com/IAM/latest/UserGuide/id_session-tags.html#id_session-tags_role-chaining)
// in the IAM User Guide.
//
// Identities
//
// 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 (http://openid.net/specs/openid-connect-core-1_0.html#Claims)
// 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 (http://openid.net/specs/openid-connect-core-1_0.html#SubjectIDTypes).

//   * ErrCodeIDPRejectedClaimException "IDPRejectedClaim"
//   The identity provider (IdP) reported that authentication failed. This might

//
//   If this error is returned for the AssumeRoleWithWebIdentity operation, it
//   can also mean that the claim has expired or has been explicitly revoked.
//
//   * ErrCodeIDPCommunicationErrorException "IDPCommunicationError"
//   The request could not be fulfilled because the identity provider (IDP) that
//   was asked to verify the incoming identity token could not be reached. This
//   is often a transient error caused by network conditions. Retry the request
//   a limited number of times so that you don't exceed the request rate. If the

// 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

//
// You can create a mobile-based or browser-based app that can authenticate

// For more information, see Federation Through a Web-based Identity Provider
// (https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_request.html#api_assumerolewithwebidentity)
// in the IAM User Guide.
//
// 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 (https://docs.aws.amazon.com/IAM/latest/UserGuide/best-practices.html)
// in the IAM User Guide.
//
// Session duration
//
// 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
// session duration 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).
//
// Permissions
//
// You can use the temporary credentials created by GetFederationToken in any
// AWS service except the following:
//
//    * You cannot call any IAM operations using the AWS CLI or the AWS API.
//
//    * You cannot call any STS operations except GetCallerIdentity.
//
// You must pass an inline or managed session policy (https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies.html#policies_session)
// 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 can't exceed 2,048 characters.
//
// Though the session policy parameters are optional, if you do not pass a policy,
// then the resulting federated user session has no permissions. 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 (https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies.html#policies_session)
// in the IAM User Guide. For information about using GetFederationToken to
// create temporary security credentials, see GetFederationToken—Federation
// Through a Custom Identity Broker (https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_request.html#api_getfederationtoken).
//
// You can use the credentials to access a resource that has a resource-based
// policy. If that policy specifically references the federated user session
// in the Principal element of the policy, the session has the permissions allowed
// by the policy. These permissions are granted in addition to the permissions
// granted by the session policies.
//
// Tags
//

// GetSessionToken API operation for AWS Security Token Service.
//
// 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 (https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_request.html)
// and Comparing the AWS STS API operations (https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_temp_request.html#stsapi_comparison)
// in the IAM User Guide.
//
// Session Duration
//
// 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.
//
// Permissions
//
// 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.
//
// We recommend that you do not call GetSessionToken with AWS account root user
// credentials. Instead, follow our best practices (https://docs.aws.amazon.com/IAM/latest/UserGuide/best-practices.html#create-iam-users)
// by creating one or more IAM users, giving them the necessary permissions,
// and using IAM users for everyday interaction with AWS.
//
// 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.
//
// For more information about using GetSessionToken to create temporary credentials,
