// Returns the lifecycle configuration information set on the bucket. For
// information about lifecycle configuration, see [Object Lifecycle Management].
//
// Bucket lifecycle configuration now supports specifying a lifecycle rule using
// an object key name prefix, one or more object tags, object size, or any
// combination of these. Accordingly, this section describes the latest API, which
// is compatible with the new functionality. The previous version of the API
// supported filtering based only on an object key name prefix, which is supported
// for general purpose buckets for backward compatibility. For the related API
// description, see [GetBucketLifecycle].
//
// Lifecyle configurations for directory buckets only support expiring objects and
// cancelling multipart uploads. Expiring of versioned objects, transitions and tag
// filters are not supported.
//
// Permissions
//   - General purpose bucket permissions - By default, all Amazon S3 resources
//     are private, including buckets, objects, and related subresources (for example,
//     lifecycle configuration and website configuration). Only the resource owner
//     (that is, the Amazon Web Services account that created it) can access the
//     resource. The resource owner can optionally grant access permissions to others
//     by writing an access policy. For this operation, a user must have the
//     s3:GetLifecycleConfiguration permission.
//
// For more information about permissions, see [Managing Access Permissions to Your Amazon S3 Resources].
//
//   - Directory bucket permissions - You must have the
//     s3express:GetLifecycleConfiguration permission in an IAM identity-based policy
//     to use this operation. Cross-account access to this API operation isn't
//     supported. The resource owner can optionally grant access permissions to others
//     by creating a role or user for them as long as they are within the same account
//     as the owner and resource.
//
// For more information about directory bucket policies and permissions, see [Authorizing Regional endpoint APIs with IAM]in
//
//	the Amazon S3 User Guide.
//
// Directory buckets - For directory buckets, you must make requests for this API
//
//	operation to the Regional endpoint. These endpoints support path-style requests
//	in the format https://s3express-control.region-code.amazonaws.com/bucket-name
//	. Virtual-hosted-style requests aren't supported. For more information about
//	endpoints in Availability Zones, see [Regional and Zonal endpoints for directory buckets in Availability Zones]in the Amazon S3 User Guide. For more
//	information about endpoints in Local Zones, see [Concepts for directory buckets in Local Zones]in the Amazon S3 User Guide.
//
// HTTP Host header syntax  Directory buckets - The HTTP Host header syntax is

// GetBucketLifecycleConfiguration has the following special error:
//
//   - Error code: NoSuchLifecycleConfiguration

//   - Description: The lifecycle configuration does not exist.

//
//   - SOAP Fault Code Prefix: Client
//
// The following operations are related to GetBucketLifecycleConfiguration :
//
// [GetBucketLifecycle]
//
// [PutBucketLifecycle]
//
// [DeleteBucketLifecycle]
//
// You must URL encode any signed header values that contain spaces. For example,
// if your header value is my file.txt , containing two spaces after my , you must
// URL encode this value to my%20%20file.txt .
