Destructors

Source

val kind : 
  Evd.evar_map ->
  t ->
  (t, t, ESorts.t, EInstance.t) Constr.kind_of_term

Same as Constr.kind except that it expands evars and normalizes universes on the fly.

Source

val kind_upto : 
  Evd.evar_map ->
  Constr.t ->
  (Constr.t, Constr.t, Sorts.t, UVars.Instance.t) Constr.kind_of_term

Sourceval to_constr : ?abort_on_undefined_evars:bool -> Evd.evar_map -> t -> Constr.t

Returns the evar-normal form of the argument. Note that this function is supposed to be called when the original term has not more free-evars anymore. If you need compatibility with the old semantics, set abort_on_undefined_evars to false.

For getting the evar-normal form of a term with evars see Evarutil.nf_evar.

Sourceval to_constr_opt : Evd.evar_map -> t -> Constr.t option

Same as to_constr, but returns None if some unresolved evars remain

Sourcetype kind_of_type =

| CastType of types * t
| ProdType of Names.Name.t Context.binder_annot * t * t
