type t

Represents the shortest unambiguous path through the Computation.t data structure, including the path through any contained Value.ts. Several of the constructors in Computation.t only contain a single inner computation or value; thus, keeping track of these segments in all the paths is often unnecessary. Thus, we can more properly model this path as with two parts:

  • the list of choices made; nodes which do not require a choice do not make it into the list.
  • a number representing the amount of nodes descended into after the last choice point.

Whenever a choice point gets added, we reset the number of nodes descended back to 0, since that number is no longer helpful for keeping the paths unique.

The of_string and to_string functions operate on short, yet semi-human-readable strings.

For example:

{ choices = [ 1; 2; 3]; descend = 4 }

is serialized to "1-2-3_4"

include Core.Stringable.S with type t := t
val of_string : string -> t
val to_string : t -> string
type builder
val empty : builder

The empty node path.

val choice_point : builder -> int -> builder

Adds a choice point to that input path. The provided number says which of the choices at that point was taken. When traversing a computation or value, if any case has multiple recursive calls, you should add a choice point to the path built up in each of those calls, with each call using a different number.

val descend : builder -> builder

Adds an extra segment to the input path. All such segments get forgotten when the next choice point is added.

val finalize : builder -> t
