Module Shape.Uid
A Uid.t is associated to every declaration in signatures and implementations. They uniquely identify bindings in the program. When associated with these bindings' locations they are useful to external tools when trying to jump to an identifier's declaration or definition. They are stored to that effect in the uid_to_decl table of cmt files.

include Hashtbl.HashedType with type t := T.t
val hash : T.t -> intA hashing function on keys. It must be such that if two keys are equal according to equal, then they have identical hash values as computed by hash. Examples: suitable (equal, hash) pairs for arbitrary key types include
- (
(=),hash) for comparing objects by structure (provided objects do not contain floats) - (
(fun x y -> compare x y = 0),hash) for comparing objects by structure and handlingStdlib.nancorrectly - (
(==),hash) for comparing objects by physical equality (e.g. for mutable or cyclic objects).
include Map.OrderedType with type t := T.t
A total ordering function over the keys. This is a two-argument function f such that f e1 e2 is zero if the keys e1 and e2 are equal, f e1 e2 is strictly negative if e1 is smaller than e2, and f e1 e2 is strictly positive if e1 is greater than e2. Example: a suitable ordering function is the generic structural comparison function Stdlib.compare.
