// This operation lists in-progress multipart uploads for the specified vault. An
// in-progress multipart upload is a multipart upload that has been initiated by an
// InitiateMultipartUpload request, but has not yet been completed or aborted. The
// list returned in the List Multipart Upload response has no guaranteed order. The
// List Multipart Uploads operation supports pagination. By default, this operation
// returns up to 50 multipart uploads 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 multipart uploads that begins at a
// specific upload, set the marker request parameter to the value you obtained
// from a previous List Multipart Upload request. You can also limit the number of
// uploads returned in the response by specifying the limit parameter in the
// request. Note the difference between this operation and listing parts ( ListParts
// ). The List Multipart Uploads operation lists all multipart uploads for a vault
// and does not require a multipart upload ID. The List Parts operation requires a
// multipart upload ID since parts are associated with a single upload. 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) (https://docs.aws.amazon.com/amazonglacier/latest/dev/using-iam-with-amazon-glacier.html)
// . For conceptual information and the underlying REST API, see Working with
// Archives in Amazon S3 Glacier (https://docs.aws.amazon.com/amazonglacier/latest/dev/working-with-archives.html)
// and List Multipart Uploads  (https://docs.aws.amazon.com/amazonglacier/latest/dev/api-multipart-list-uploads.html)
