创建任务时返回的错误


Error returned when spawning a task.

Variants§

§

Busy

此任务正在运行的实例太多。

默认情况下,一个被 #[embassy_executor::task] 标记的任务,在运行期间,只能有一个实例。 你可以使用 #[embassy_executor::task(pool_size = 4)] 来让多个实例并行运行,这也会 消耗更多的内存。


Too many instances of this task are already running.

By default, a task marked with #[embassy_executor::task] can only have one instance running at a time. You may allow multiple instances to run in parallel with #[embassy_executor::task(pool_size = 4)], at the cost of higher RAM usage.
