minibytes

This create provides the Bytes type. It is similar to &[u8]: cloning or slicing are zero-copy. Unlike &[u8], Bytes does not have lifetime. This is done by maintaining the life cycle of the underlying storage using reference count.

Aside from supporting Vec<u8> as the underlying storage, Bytes also supports memmap::Mmap. Libraries can implement BytesOwner for other types to further extend storage support.
