The bytes crate does support what ComputerGuru asked for via the Buf trait. The trait can be implemented over a sequence of buffers but still provides functions that are common with single buffers. For example the hyper crate uses the trait in exactly this way - it has an internal type that is a VecDeque of chunks but also implements the Buf trait.
