Crate qubit_codec 

qubit-codec

Core codec traits and buffer conversion primitives for Rust applications.

This crate contains only domain-neutral building blocks such as value codecs, owned value encoder/decoder helpers, byte-order markers, and progress-oriented buffer transcoders. The only I/O-facing types are the low-level qubit_io::Input/qubit_io::Output bridges used by downstream stream crates. Concrete binary, text, misc, and std::io adapters live in sibling crates.

Macros
