AsyncSlotState enum
The finite-state-machine state of an async slot (docs/async.md § Async slot state machine).
Values
- empty → const AsyncSlotState
-
No cached value, no in-flight computation. Entered on creation and after a hard clear.
- computing → const AsyncSlotState
-
A handle tracks the in-flight future for the current revision. Concurrent
getAsynccallers attach as waiters to the same in-flight result instead of spawning duplicate futures. - resolved → const AsyncSlotState
-
The cached value is fresh, until dependency invalidation transitions back to computing.
- error → const AsyncSlotState
-
The last computation failed; callers receive the error or retry on the next
getAsync.
