Module Structure

module Structure: sig .. end
Gadt describing the structure of a tree of different data types, and providing fast accessors of its nodes. The leafs must provide a key from a Key module, see key.mli for details.

type ('_, '_) eq = 
| Eq : ('a, 'a) eq
Equality witness between types.
module type Key = sig .. end
Keys identifying datatypes.
module type Shape = sig .. end
A Key module with its structure type.
module Make: 
functor (X : sig
end) -> Shape
module Key_Value: Shape 
Keys module for the abstract values of Eva.
module Key_Location: Shape 
Keys module for the abstract locations of Eva.
module Key_Domain: Shape 
Keys module for the abstract domains of Eva.
module type Internal = sig .. end
Internal view of the tree, with the structure.
module type External = sig .. end
External view of the tree, with accessors.
module Open: 
functor (Shape : Shape) ->
functor (Data : Internal with type 'a structure := 'a Shape.structure) -> External with type t := Data.t and type 'a key := 'a Shape.k
Opens an internal tree module into an external one.
