RequireImport Ltac2.Init.
Ltac2 Type t := projection. (** Type of primitive projections. This includes the unfolding boolean. *)
Ltac2 @ external equal : t -> t -> bool := "rocq-runtime.plugins.ltac2""projection_equal". (** Projections obtained through module aliases or Include are not
considered equal by this function. The unfolding boolean is not ignored. *)
Ltac2 @ external ind : t -> inductive := "rocq-runtime.plugins.ltac2""projection_ind". (** Get the inductive to which the projectin belongs. *)
Ltac2 @ external index : t -> int := "rocq-runtime.plugins.ltac2""projection_index". (** The index of the projection indicates which field it projects. *)
Ltac2 @ external unfolded : t -> bool := "rocq-runtime.plugins.ltac2""projection_unfolded". (** Get the unfolding boolean. *)
Ltac2 @ external set_unfolded : t -> bool -> t
:= "rocq-runtime.plugins.ltac2""projection_set_unfolded". (** Set the unfolding boolean. *)
Ltac2 @ external of_constant : constant -> t option
:= "rocq-runtime.plugins.ltac2""projection_of_constant". (** Get the primitive projection associated to the constant. The returned projection is folded.
Returns [None] when the constant is not associated to a primitive projection. *)
Ltac2 @ external to_constant : t -> constant option
:= "rocq-runtime.plugins.ltac2""projection_to_constant". (** Get the constant associated to the primitive projection.
Currently always returns [Some] but this may change in the future. *)
