bytering::Buffer

A simple ring buffer with fixed capacity specialized for vectored reading and writing in blocking and async I/O.

Similar to VecDeque it provides a pair of byte slices in correct order to the filled regions of its internal linear space. Unlike VecDeque it also provides pairs of mutable slices for writing into the empty region or regions. These pairs of slices can be directly passed to read_vectored and write_vectored.

If neither source nor target of data has optimized vectored I/O this ring buffer does not offer any advantages.
