Standard Library
Below is the API for the OCaml standard library. It's directly copied over from the OCaml Manual, formatted to the Reason syntax and styled accordingly. The API docs are work-in-progress; we'll be polishing these gradually!
If you're targeting JavaScript, the API docs for BuckleScript includes all of below, plus JS-specific APIs.
Module Oo
module Oo: sig .. end
Operations on objects
val copy : (< .. > as 'a) -> 'a
Oo.copy o returns a copy of object o, that is a fresh
object with the same methods and instance variables as o.val id : < .. > -> int
Return an integer identifying this object, unique for
the current execution of the program. The generic comparison
and hashing functions are based on this integer. When an object
is obtained by unmarshaling, the id is refreshed, and thus
different from the original object. As a consequence, the internal
invariants of data structures such as hash table or sets containing
objects are broken after unmarshaling the data structures.
