This function is similar to write_async, but takes a Bytes as input.
Due to the refcounted nature of Bytes, this allows the stream to avoid taking a copy of the data.
However, note that this function may still perform partial writes, just like write_async. If that occurs, to continue writing, you will need to create a new Bytes containing just the remaining bytes, using Bytes.from_bytes . Passing the same Bytes instance multiple times potentially can result in duplicated data in the output stream.
For the synchronous, blocking version of this function, see write_bytes.
