serde.ml

A serialization framework for OCaml inspired by serde-rs.

The main goals for serde.ml are:

type rank = Captain | Chief_petty_officer [@@deriving serialize, deserialize]
type t = { name : string; rank : rank } [@@deriving serialize, deserialize]

let obrien = { name = "Miles O'Brien"; rank = Chief_petty_officer }
let sisko = { name = "Benjamin Sisko"; rank = Captain }

> Serde_json.to_string_pretty (serialize_t) obrien
Ok "{ \"name\": \"Miles O'Brien\", \"rank\": \"Chief_petty_officer\" }"

> Serde_json.of_string (deserialize_t) "{ \"name\": \"Miles O'Brien\", \"rank\": \"Chief_petty_officer\" }"
Ok {name = "Miles O'Brien"; rank = Chief_petty_officer}

> Serde_sexpr.to_string_pretty (serialize_t) obrien;;
Ok "(\"Miles O'Brien\" :Chief_petty_officer)"

> Serde_sexpr.of_string (deserialize_t) "(\"Miles O'Brien\" :Chief_petty_officer)";;
Ok {name = "Miles O'Brien"; rank = Chief_petty_officer}

Installation

To install serde from opam, use:

; opam install serde serde_derive serde_json -y

To install serde from sources, use:

; opam pin serde.0.0.2 git+https://github.com/serde-ml/serde -y
; opam pin serde_derive.0.0.2 git+https://github.com/serde-ml/serde -y
; opam pin serde_json.0.0.2 git+https://github.com/serde-ml/serde -y

Usage

To derive deserialize/serialize functions for your data types, make sure to

Now you can add @@deriving annotations to your types:

type rank = Captain | Chief_petty_officer [@@deriving serialize, deserialize]
type t = { name : string; rank : rank } [@@deriving serialize, deserialize]

And use them with the formats:

Serde_json.to_string serialize_rank { name = "Benjamin Sisko"; rank = Captain }
