Data-encoding

A library for encoding and decoding data. It offers a great degree of control over the layout of data. It supports json and binary serialisation/deserialisation.

Usage

For a type t, you can use the library's combinators to build an encoding t encoding. You can then use the various reading/writing functions with this encoding to serialise and deserialise values of the type t.

Example:

open Data_encoding

type t = (string * int) list
let encoding = list (tup2 string int31)
let v = [("foo", 32); ("bar", 0)]
let j = Json.construct encoding v
let w = Json.destruct encoding j
let () = assert (v = w)
