metadata property
Service-specific metadata associated with the operation. It typically contains progress information and common metadata such as create time. Some services might not provide such metadata. Any method that returns a long-running operation should document the metadata type, if any.
Implementation
@$pb.TagNumber(2)
$2.Any get metadata => $_getN(1);

@$pb.TagNumber(2)
set metadata($2.Any v) {
setField(2, v);
