include Identifiable.Thing with type t := Label.T.t

include Stdlib.Hashtbl.HashedType with type t := Label.T.t

val hash : Label.T.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

((=), hash) for comparing objects by structure (provided objects do not contain floats)
((fun x y -> compare x y = 0), hash) for comparing objects by structure and handling Stdlib.nan correctly
((==), hash) for comparing objects by physical equality (e.g. for mutable or cyclic objects).

include Stdlib.Map.OrderedType with type t := Label.T.t

val compare : Label.T.t -> Label.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.

val output : Stdlib.out_channel -> Label.T.t -> unit

val reset : unit -> unit

val to_int : Label.t -> int

val of_int_unsafe : int -> Label.t

of_int_unsafe is used for testing and ocamlfdo.
