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.
