Module UVars.InstanceSource

Sourcetype t

A universe instance represents a vector of argument universes and sort qualities to a polymorphic definition (constant, inductive or constructor).

Sourceval empty : t
Sourceval is_empty : t -> bool
Sourceval of_array : (Sorts.Quality.t array * Univ.Level.t array) -> t
Sourceval to_array : t -> Sorts.Quality.t array * Univ.Level.t array
Sourceval abstract_instance : (int * int) -> t

Instance of the given size made of QVar/Level.var

Sourceval append : t -> t -> t

To concatenate two instances, used for discharge

Sourceval equal : t -> t -> bool

Equality

Sourceval length : t -> int * int

Instance length

Sourceval hcons : t -> t

Hash-consing.

Sourceval hash : t -> int

Hash value

Sourceval share : t -> t * int

Simultaneous hash-consing and hash-value computation

Sourceval pr : (Sorts.QVar.t -> Pp.t) -> (Univ.Level.t -> Pp.t) -> ?variance:Variance.t array -> t -> Pp.t

Pretty-printing, no comments

The set of levels in the instance

Sourceval subst_fn : ((Sorts.QVar.t -> Sorts.Quality.t) * (Univ.Level.t -> Univ.Level.t)) -> t -> t
