Module Deriving_Json

Typesafe IO (based on the deriving library).

type 'a t

The type of JSON parser/printer for value of type 'a.

val make : (Buffer.t -> 'a -> unit) -> (Deriving_Json_lexer.lexbuf -> 'a) -> 'a t
val write : 'a t -> Buffer.t -> 'a -> unit
val read : 'a t -> Deriving_Json_lexer.lexbuf -> 'a
val to_string : 'a t -> 'a -> string

to_string Json.t<ty> v marshal the v of type ty to a JSON string.

val from_string : 'a t -> string -> 'a

from_string Json.t<ty> s safely unmarshal the JSON s into an OCaml value of type ty. Throws Failure if the received value isn't the javascript representation of a value of type ty.

module type Json = sig ... end

The signature of the JSON class.
