The Rust MessagePack Library

RMP is a pure Rust MessagePack implementation.

MessagePack is an efficient binary serialization format.

Warning this library is still in rapid development and everything may change until 1.0 comes.


To use rmp, first add this to your Cargo.toml:

rmp = "0.7.0"

Then, add this to your crate root:

extern crate rmp as msgpack;


  • Convenient API

    RMP is designed to be lightweight and straightforward. There are low-level API, which gives you full control on data encoding/decoding process and makes no heap allocations. On the other hand there are high-level API, which provides you convenient interface using Rust standard library and compiler reflection, allowing to encode/decode structures using derive attribute.

  • Zero-copy value decoding

    RMP allows to decode bytes from a buffer in a zero-copy manner easily and blazingly fast, while Rust static checks guarantees that the data will be valid until buffer lives.

  • Clear error handling

    RMP's error system guarantees that you never receive an error enum with unreachable variant.

  • Robust and tested

    This project is developed using TDD and CI, so any found bugs will be fixed without breaking existing functionality.
