Module `Type_immediacy`

Immediacy status of a type

type t =

| Unknown
(*
We don't know anything
*)
| Always
(*
We know for sure that values of this type are always immediate
*)
| Always_on_64bits
(*
We know for sure that values of this type are always immediate on 64 bit platforms. For other platforms, we know nothing.
*)

module Violation : sig ... end

val coerce : 
  Type_immediacy.t ->
  as_:Type_immediacy.t ->
  (unit, Type_immediacy.Violation.t) Stdlib.result

coerce t ~as_ returns Ok () iff t can be seen as type immediacy as_. For instance, Always can be seen as Always_on_64bits but the opposite is not true. Return Error _ if the coercion is not possible.

val of_attributes : Parsetree.attributes -> Type_immediacy.t

Return the immediateness of a type as indicated by the user via attributes
