Module `Weak_array`Source

Module for dealing with weak pointers, i.e., pointers that don't prevent garbage collection of what they point to.

This module 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.

Sourcetype 'a t

Sourceval sexp_of_t : ('a -> Sexplib0.Sexp.t) -> 'a t -> Sexplib0.Sexp.t

Sourceval create : len:Base.int -> _ t

Sourceval length : _ t -> Base.int

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

Sourceval set_exn : 'a t -> Base.int -> 'a Base.option -> Base.unit

set_exn raises an exception if given Some x with x not being a heap block. This is in addition to raising exceptions on bounds violation as set does.

Sourceval get : 'a t -> Base.int -> 'a Heap_block.t Base.option

Sourceval is_some : _ t -> Base.int -> Base.bool

Sourceval is_none : _ t -> Base.int -> Base.bool

Sourceval iter : 'a t -> f:('a -> Base.unit) -> Base.unit

Sourceval iteri : 'a t -> f:(Base.int -> 'a -> Base.unit) -> Base.unit

val blit : 
  src:'a t ->
  src_pos:Base.int ->
  dst:'a t ->
  dst_pos:Base.int ->
  len:Base.int ->
  Base.unit

blit is generally preferred over get followed by set because, unlike get, it doesn't have to make the value strongly-referenced. Making a value strongly-referenced, even temporarily, may result in delaying its garbage collection by a whole GC cycle.
