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
is provided for routine visualization of biniou data files.
can be used to derive OCaml-Biniou serializers and deserializers
from type definitions.
The development version of Biniou is hosted on GitHub.
