Crate io_buffer

io-buffer

This crate provide a Buffer type, to unify the difference of different types of buffer, for disk and network IO:

• Converts owned buffer, From<Vec<u8>> and To<Vec<u8>>.

• Allocation with malloc()

• Allocation with posix_memalign()

• Converts from const reference, or from mutable reference of unsafe c code.

On debug mode, provides runtime checking if you try to as_mut() a const buffer.

Cargo.toml:
