RMP is a complete pure-Rust implementation of the MessagePack binary serialization format, provided as three crates: a low-level encoder/decoder, a Serde integration, and a dynamic Value type. It supports zero-copy decoding, no-std usage, and schema-less deserialization.

Use cases

• serialize Rust structs to MessagePack with Serde derive
• decode MessagePack messages without a known schema
• encode and decode binary data in a compact format instead of JSON
• parse MessagePack streams with zero-copy decoding
• use MessagePack in embedded or no-std Rust environments

When to choose

• you need a compact, self-describing binary format in Rust with Serde support
• you want schema-less deserialization of arbitrary MessagePack payloads
• you need no-std or allocation-free encoding/decoding

When to avoid

• you need bignums, dates, or other CBOR-only data types
• your data exchange requires JSON compatibility or human readability
