Derived generators

val strf : ('a, Stdlib.Format.formatter, unit, t) Stdlib.format4 -> 'a

strf fmt ... is a JSON string generated value formatted according to fmt.

val option : ('a -> t) -> 'a option -> t

option some o is o as a generated JSON value which is null if o is None and some v if o is some v.

list el l is l as a generated JSON array whose elements are generated using el.

val json : Json.t -> t

of_json v is the JSON value v as a generated value.
