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.
