May I suggest the bytes crate [0]? It's one of those small libraries providing a key building block (mutable and immutable byte buffers), and is a dependency of tokio-io and any other crate which implements tokio-io's Encoder/Decoder traits.

Yes, thank you for the suggestion. I agree that's a good candidate and will note it on thread.
