psq — Functional Priority Search Queues

v0.1.1

psq provides a functional priority search queue for OCaml. This structure behaves both as a finite map, containing bindings k -> p, and a priority queue over p. It provides efficient access along more than one axis: to any binding by k, and to the binding(s) with the least p.

Typical applications are searches, schedulers and caches. If you ever scratched your head because that A* didn't look quite right, a PSQ is what you needed.

The implementation is backed by priority search pennants.

psq is distributed under the ISC license.
