Description

Added to opam-repository:

README

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)

Tutorial

A full tutorial is available in markdown form in src/tutorial.md.

It is available online on ocaml.org's package documentation and on data-encoding's own online documentation.

Build status

Results of building data-encoding with each compiler on check.ci.ocaml.org, run of against opam-repository 7cdc698. All results for this package.

Each result links to its build log. To keep crawlers from overloading the site, build logs require a GitHub sign-in (see ocurrent/opam-health-check). On your first log, GitHub asks you to “Authorize opam-health-check”, the OCurrent app that runs these checks; it sees only your public profile, not your repositories. The sign-in lasts 30 days.
