// Returns a list of all Amazon S3 directory buckets owned by the authenticated
// sender of the request. For more information about directory buckets, see [Directory buckets]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.
//
// Permissions You must have the s3express:ListAllMyDirectoryBuckets permission in
// an IAM identity-based policy instead of a bucket policy. Cross-account access to
// this API operation isn't supported. This operation can only be performed by the
// Amazon Web Services account that owns the resource. For more information about
// directory bucket policies and permissions, see [Amazon Web Services Identity and Access Management (IAM) for S3 Express One Zone]in the Amazon S3 User Guide.
//
// HTTP Host header syntax  Directory buckets - The HTTP Host header syntax is
// s3express-control.region.amazonaws.com .
//
// The BucketRegion response element is not part of the ListDirectoryBuckets
// Response Syntax.
//
// 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 .
