Event & Task Utilities

Async building blocks: a cooperatively cancellable spawned task and a one-shot await/signal latch.

Original, compile-verified Verse by Bizanator (Biloxi Studios). Clean-room sample you can drop into a UEFN project and adapt.

  # Lightweight building blocks for async coordination: a cooperatively cancellable
  # task you can stop from the outside, and a tiny one-shot latch you can await and
  # signal across concurrent code. Dependency-free.
  #
  # Teaches: spawn/await, the <suspends> effect, classes implementing awaitable(t),
  # cooperative cancellation (tasks can't be force-killed — they check a flag), and
  # Verse's `event` type for cross-task signalling.
  #
  # Example — cancellable task:
  #   Task := SpawnCancellable(MyWork)   # MyWork(State)<suspends>:void
  #   Task.Cancel()                      # ask it to stop at its next check
  #
  # Example — one-shot latch:
  #   Latch := one_shot{}
  #   spawn{ Latch.Await(); DoSomethingOnce() }
  #   Latch.Signal()                     # releases the awaiter exactly once
