Module CCPersistentHashtbl

module CCPersistentHashtbl: sig .. end

Persistent hash-table on top of OCaml's hashtables

Almost as efficient as the regular Hashtbl type, but with a persistent interface (rewinding changes to get back in the past history). This is mostly useful for backtracking-like uses, or forward uses (never using old values).

This module is not thread-safe.

type 'a sequence = ('a -> unit) -> unit

type 'a printer = Format.formatter -> 'a -> unit

type 'a equal = 'a -> 'a -> bool

module type HashedType = sig .. end

Signature of such a hashtable

module type S = sig .. end

Implementation

module Make (H : HashedType) : S  with type key = H.t
