Module `Tac2dyn.Val`

Toplevel values

type 'a tag: Type of dynamic tags

type t = | Dyn : 'a tag * 'a -> t Type of dynamic values

val create : string -> 'a tag: create n returns a tag describing a type called n. create raises an exception if n is already registered. Type names are hashed, so create may raise even if no type with the exact same name was registered due to a collision.

val anonymous : int -> 'a tag: anonymous i returns a tag describing an i-th anonymous type. If anonymous is not used together with create, max_int anonymous types are available. anonymous raises an exception if i is already registered.

val eq : 'a tag -> 'b tag -> ('a, 'b) CSig.eq option: eq t1 t2 returns Some witness if t1 is the same as t2, None otherwise.

val repr : 'a tag -> string: repr tag returns the name of the type represented by tag.

val dump : unit -> (int * string) list: dump () returns a list of (tag, name) pairs for every type tag registered in this Dyn.Make instance.

type any = | Any : 'a tag -> any Type of boxed dynamic tags

val name : string -> any option: name n returns Some t where t is a boxed tag previously registered with create n, or None if there is no such tag.
