Sourceval checked_universes : UGraph.t universe_compare

These two never raise UnivInconsistency, inferred_universes just gathers the constraints.

These two functions can only raise NotConvertible

Sourceval infer_conv : ?l2r:bool -> ?evars:(Constr.existential -> Constr.constr option) -> ?ts:TransparentState.t -> Constr.constr infer_conversion_function

These conversion functions are used by module subtyping, which needs to infer universe constraints inside the kernel

Sourceval infer_conv_leq : ?l2r:bool -> ?evars:(Constr.existential -> Constr.constr option) -> ?ts:TransparentState.t -> Constr.types infer_conversion_function

Depending on the universe state functions, this might raise UniverseInconsistency in addition to NotConvertible (for better error messages).

Sourceval beta_applist : Constr.constr -> Constr.constr list -> Constr.constr

Builds an application node, reducing beta redexes it may produce.

Sourceval beta_appvect : Constr.constr -> Constr.constr array -> Constr.constr

Builds an application node, reducing beta redexes it may produce.

Builds an application node, reducing beta redexe it may produce.

Sourceval hnf_prod_applist : Environ.env -> Constr.types -> Constr.constr list -> Constr.types

Pseudo-reduction rule Prod(x,A,B) a --> Bx\a

Sourceval hnf_prod_applist_assum : Environ.env -> int -> Constr.types -> Constr.constr list -> Constr.types

In hnf_prod_applist_assum n c args, c is supposed to (whd-)reduce to the form ∀Γ.t with Γ of length n and possibly with let-ins; it returns t with the assumptions of Γ instantiated by args and the local definitions of Γ expanded.

Sourceval betazeta_appvect : int -> Constr.constr -> Constr.constr array -> Constr.constr

Compatibility alias for Term.lambda_appvect_assum
