NAME¶

MoreLabels.Hashtbl.Make - Functor building an implementation of the hashtable structure.

Module¶

Module MoreLabels.Hashtbl.Make

Documentation¶

Module Make
: functor (H : HashedType) -> sig end

Functor building an implementation of the hashtable structure. The functor Hashtbl.Make returns a structure containing a type key of keys and a type 'a t of hash tables associating data of type 'a to keys of type key . The operations perform similarly to those of the generic interface, but use the hashing and equality functions specified in the functor argument H instead of generic equality and hashing. Since the hash function is not seeded, the create operation of the result structure always returns non-randomized hash tables.

Parameters:

"H"
