Toplevel definition of types
Toplevel definition of algebraic constructors
type constructor_data = {
cdata_prms : int;(*

Type parameters

*)
cdata_type : Tac2expr.type_constant;(*

Inductive definition to which the constructor pertains

*)
cdata_args : int Tac2expr.glb_typexpr list;(*

Types of the constructor arguments

*)
cdata_indx : int option;(*

Index of the constructor in the ADT. Numbering is duplicated between argumentless and argument-using constructors, e.g. in type 'a option None and Some have both index 0. This field is empty whenever the constructor is a member of an open type.

Useful for printing info about currently defined constructors of open types.

Toplevel definition of projections

Type parameters

*)

Record definition to which the projection pertains
