Module executor 

Single-owner coroutine execution with interrupt-safe wake publication.

Futures are polled and destroyed only by the owner thread. Wakers may cross CPUs and may run in hard interrupt context; their operations only touch atomics, publish intrusive nodes, and invoke a direct thread wake header. Zero-reference allocations are freed immediately in task context; hard IRQ transfers only the typed coroutine header to the task-work reaper.

Structs

CoroutineHeader

Pinned header addressed directly by the coroutine’s custom raw waker.

CoroutineId

Generation-bearing identity of one coroutine owned by a local executor.

ExecutorParkCondition

Borrowed executor predicate for one OS scheduler park attempt.

LocalExecutor

A single-thread executor whose owner may migrate between CPUs.

ParkToken

Proof that the owner completed the executor-side park handshake.

PollBatch

Outcome of one bounded executor turn.

Enums

BlockOnError

Error returned when a runtime-local future misses its monotonic deadline.

Constants

DEFAULT_POLL_BATCH

Maximum number of futures polled by one executor turn.

Functions

block_on

Polls a future to completion on the calling runtime scheduler thread.

block_on_timeout

Polls a future until completion or a relative monotonic timeout.

wake_waker_sync

Wakes a coroutine with Linux WF_SYNC scheduling semantics.
