Skuld.Comp.ExternalSuspend (skuld v0.1.26)

View Source

External suspension for yielding to code outside Skuld's env threading.

Unlike InternalSuspend (which receives env at resume time), this suspension closes over the env at suspension point. Use this when:

  • Yielding values to external code that doesn't understand Skuld's env
  • The Yield effect's coroutine-style suspension
  • Any suspension where the caller will provide a value but not an updated env

Resume Signature

resume :: (val) -> {result, env} - closes over env from suspension point

The :data field holds decorations added by scoped effects via transform_suspend. Default is nil to distinguish "no decorations" from "empty decorations map".
