| 1 | # embassy-executor | ||
| 2 | |||
| 3 | An async/await executor designed for embedded usage. | ||
| 4 | |||
| 5 | - No `alloc`, no heap needed. Task futures are statically allocated. | ||
| 6 | - No "fixed capacity" data structures, executor works with 1 or 1000 tasks without needing config/tuning. | ||
| 7 | - Integrated timer queue: sleeping is easy, just do `Timer::after(Duration::from_secs(1)).await;`. | ||
| 8 | - No busy-loop polling: CPU sleeps when there's no work to do, using interrupts or `WFE/SEV`. | ||
| 9 | - Efficient polling: a wake will only poll the woken task, not all of them. | ||
| 10 | - Fair: a task can't monopolize CPU time even if it's constantly being woken. All other tasks get a chance to run before a given task gets polled for the second time. | ||
| 11 | - Creating multiple executor instances is supported, to run tasks with multiple priority levels. This allows higher-priority tasks to preempt lower-priority tasks. | ||
