Sourceval checked_universes : UGraph.t universe_compare

This function never raise UnivInconsistency.

Sourceval conv : Constr.constr extended_conversion_function

These two functions can only raise NotConvertible

val generic_conv : 
  conv_pb ->
  l2r:bool ->
  Constr.constr Constr.evar_handler ->
  TransparentState.t ->
  (Constr.constr, 'a) generic_conversion_function

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

Sourceval default_conv : conv_pb -> Constr.types kernel_conversion_function

Sourceval default_conv_leq : Constr.types kernel_conversion_function

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.

Sourceval beta_app : Constr.constr -> Constr.constr -> Constr.constr

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

Source

val 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.
