Bytesbuf Io

Asynchronous I/O abstractions expressed via bytesbuf types.

These types model byte sources that can be read from (Read trait) and byte sinks that can be written to (Write trait). All operations use byte sequences represented by types from bytesbuf instead of raw byte slices, enabling the level of flexibility required for implementing and using high-performance I/O endpoints that consume or produce byte streams.

All operations are asynchronous and take ownership of the data/buffers passed to them, enabling efficient implementation of high-performance I/O endpoints with zero-copy semantics.

The futures-stream feature enables integration with the futures crate, providing an adapter that exposes a Read implementation as a futures::Stream of byte sequences.

The test-util feature enables additional utilities for testing implementations of types that produce or consume streams of bytes. These are in the testing module.
