  • 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 as long as the 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.


  • Rust 1.53.0 or later
