Module `Evar`Source

This module defines existential variables, which are isomorphic to int. Nonetheless, casting from an int to a variable is deemed unsafe, so that to keep track of such casts, one has to use the provided unsafe_of_int function.

Sourcetype t

Type of existential variables.

Sourceval repr : t -> int

Recover the underlying integer.

Sourceval unsafe_of_int : int -> t

This is not for dummies. Do not use this function if you don't know what you are doing.

Sourceval equal : t -> t -> bool

Equality over existential variables.

Sourceval compare : t -> t -> int

Comparison over existential variables.

Sourceval hash : t -> int

Hash over existential variables.

Sourceval print : t -> Pp.t

Printing representation

Sourcemodule Set : Set.S with type elt = t

Sourcemodule Map : CMap.ExtS with type key = t and module Set := Set
