About RMP - Rust MessagePack
From the project's README at github.com/3Hren/msgpack-rust. Lightly cleaned for readability; for the full source see the upstream repo.
RMP is a complete pure-Rust MessagePack implementation. MessagePack a compact self-describing binary serialization format.
[RMP-Serde][crates-rmps-url] ([Documentation][rmps-docs-url]), easy serializing/deserializing via Serde. [RMP-Value][crates-rmpv-url] ([Documentation][rmpv-docs-url]), a universal enum that can hold any MessagePack type. Allows deserializing arbitrary messages without a known schema. [RMP][crates-rmp-url] ([Documentation][rmp-docs-url]), low-level functions for reading/writing encoded data. Features Convenient and powerful APIs
RMP is designed to be lightweight and straightforward. There is a high-level API with support for Serde, which provides you convenient interface for encode/decode Rust's data structures using attribute. There are also low-level APIs, which give you full control over data encoding/decoding process, with no-std support and without heap allocations. Zero-copy value decoding
RMP allows to decode bytes from a buffer in a zero-copy manner. Parsing is implemented in safe Rust. Robust, stable and tested**
