// This operation lists the parts of an archive that have been uploaded in a
// specific multipart upload. You can make this request at any time during an
// in-progress multipart upload before you complete the upload (see
// CompleteMultipartUpload. List Parts returns an error for completed uploads. The
// list returned in the List Parts response is sorted by part range. The List Parts
// operation supports pagination. By default, this operation returns up to 50
// uploaded parts in the response. You should always check the response for a
// marker at which to continue the list; if there are no more items the marker is
// null. To return a list of parts that begins at a specific part, set the marker
// request parameter to the value you obtained from a previous List Parts request.
// You can also limit the number of parts returned in the response by specifying
// the limit parameter in the request. An AWS account has full permission to
// perform all operations (actions). However, AWS Identity and Access Management
// (IAM) users don't have any permissions by default. You must grant them explicit
// permission to perform specific actions. For more information, see Access Control
// Using AWS Identity and Access Management (IAM)
