public async Bytes load_bytes_async (Cancellable? cancellable = null, out string? etag_out) throws Error
Asynchronously loads the contents of this as Bytes.
If this is a resource:// based URI, the resulting bytes will reference the embedded resource instead of a copy. Otherwise, this is equivalent to calling load_contents_async and Bytes.take.
callback should call load_bytes_async.end to get the result of this asynchronous operation.
See load_bytes for more information.
