Abstract byte output stream object, to write data to a sink.
All method implementations are of noexcept
.
One may use fail() to detect whether an error has occurred.

Write to the data sink.
Moves the internal offset so that every call to write will be appended to the sink.
This method is not blocking beyond the transfer length bytes.
