Extensible binary data format,https://github.com/ocaml-community/biniou
Biniou (pronounced "be new") is a binary data format designed for speed,
safety, ease of use and backward compatibility as protocols evolve. Biniou is
vastly equivalent to JSON in terms of functionality but allows implementations
several times faster (4 times faster than yojson), with 25-35% space savings.
Biniou data can be decoded into human-readable form without knowledge of type
definitions except for field and variant names which are represented by 31-bit
hashes. A program named bdump is provided for routine visualization of biniou
The program atdgen can be used to derive OCaml-Biniou serializers and
deserializers from type definitions.
