module Core_weak

: sig

Weak is like the OCaml standard library module of the same name, except that it requires that the values in the weak set are heap blocks.

type 'a t

val create : len:int -> _ t

val length : _ t -> int

val set : 'a t -> int -> 'a Heap_block.t option -> unit

val get : 'a t -> int -> 'a Heap_block.t option

val is_some : _ t -> int -> bool

val is_none : _ t -> int -> bool

val sexp_of_t : ('a -> Sexplib.Sexp.t) -> 'a t -> Sexplib.Sexp.t
