include Identifiable.S

module T : Identifiable.Thing with type t = t
include Identifiable.Thing with type t := T.t
type t
include Stdlib.Hashtbl.HashedType with type t := t
type t

The type of the hashtable keys.

val equal : t -> t -> bool

The equality predicate used to compare keys.

val hash : t -> int

A hashing function on keys. It must be such that if two keys are equal according to equal, then they have identical hash values as computed by hash. Examples: suitable (equal, hash) pairs for arbitrary key types include

  • ((=), Hashtbl.hash) for comparing objects by structure (provided objects do not contain floats)
  • ((fun x y -> compare x y = 0), Hashtbl.hash) for comparing objects by structure and handling Stdlib.nan correctly
  • ((==), Hashtbl.hash) for comparing objects by physical equality (e.g. for mutable or cyclic objects).
include Stdlib.Map.OrderedType with type t := t
type t

The type of the map keys.

val compare : t -> t -> int

A total ordering function over the keys. This is a two-argument function f such that f e1 e2 is zero if the keys e1 and e2 are equal, f e1 e2 is strictly negative if e1 is smaller than e2, and f e1 e2 is strictly positive if e1 is greater than e2. Example: a suitable ordering function is the generic structural comparison function Stdlib.compare.
