Module Hmap.Key

module Key: sig .. end

Keys.

Keys

val create : unit -> 'a Hmap.key

create () is a new key.

Exisential keys allows to compare keys. This can be useful for functions like Hmap.filter.

type t

The type for existential keys.

val hide_type : 'a Hmap.key -> t

hide_type k is an existential key for k.

val equal : t -> t -> bool

equal k k' is true iff k and k' are the same key.

val compare : t -> t -> int

compare k k' is a total order on keys compatible with Hmap.Key.equal.
