Representation of projections from closures and blocks.

type project_closure = {

set_of_closures : Variable.t;
(*
must yield a set of closures
*)
closure_id : Closure_id.t;

}

The selection of one closure given a set of closures, required before a function defined by said set of closures can be applied. See more detailed documentation below on set_of_closures.

type move_within_set_of_closures = {

closure : Variable.t;
(*
must yield a closure
*)
start_from : Closure_id.t;
move_to : Closure_id.t;

}

The selection of one closure given another closure in the same set of closures. See more detailed documentation below on set_of_closures. The move_to closure must be part of the free variables of start_from.

type project_var = {

closure : Variable.t;
(*
must yield a closure
*)
closure_id : Closure_id.t;
var : Var_within_closure.t;

}

The selection from a closure of a variable bound by said closure. In other words, access to a function's environment. Also see more detailed documentation below on set_of_closures.

module T : Identifiable.Thing with type t = t

include Identifiable.Thing with type t := T.t

include Hashtbl.HashedType with type t := T.t

val equal : T.t -> T.t -> bool

The equality predicate used to compare keys.

val hash : T.t -> int

A 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 handling Stdlib.nan correctly
((==), hash) for comparing objects by physical equality (e.g. for mutable or cyclic objects).

include Map.OrderedType with type t := T.t

val compare : T.t -> T.t -> int

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.

val projecting_from : t -> Variable.t

Return which variable the given projection projects from.

val map_projecting_from : t -> f:(Variable.t -> Variable.t) -> t

Change the variable that the given projection projects from.
