Crate async_runtime 

A priority-aware native async runtime for the smol ecosystem.

Runtime uses an async-task based scheduler with per-worker queues, global priority injectors, work stealing, and parking workers. LocalDomain uses async-executor and is driven explicitly by its host thread, allowing it to run !Send futures. Neither runtime owns or drives an I/O reactor.

Enable the stats feature to inspect an approximate [RuntimeStats] snapshot of routing, stealing, parking, wake, and queue counters.

Structs

FallibleTask

A task handle that resolves to None if the task is cancelled.

LocalDomain

A thread-affine executor driven explicitly by the thread that creates it.

LocalSpawner

A capability for submitting Send work to a particular LocalDomain.

PriorityWeights

Relative scheduling opportunities assigned to each priority.

RunStats

Statistics from a time-budgeted LocalDomain drive.

Runtime

RuntimeBuilder

Spawner

Task

An awaitable task handle. Dropping it cancels the task.

Enums

Priority

Scheduling priority for tasks in the general worker pool.

ShutdownError

An error raised while shutting down a general runtime.

ShutdownOutcome

The result of a shutdown operation with a deadline.

SpawnError

An error returned when a task cannot be accepted.
