pub struct TaskPool<F: Future + 'static, const N: usize> { /* private fields */ }
Expand description

原始存储器,可以保存多个相同类型的任务

这本质上是一个 [TaskStorage<F>; N]


Raw storage that can hold up to N tasks of the same type.

This is essentially a [TaskStorage<F>; N].

Implementations§

source§

impl<F: Future + 'static, const N: usize> TaskPool<F, N>

source

pub const fn new() -> Self

创建一个 TaskPool, 其中的所有任务都是未创建的状态


Create a new TaskPool, with all tasks in non-spawned state.

source

pub fn spawn( &'static self, future: impl FnOnce() -> F ) -> SpawnToken<impl Sized>

尝试在池中创建任务

TaskStorage::spawn() 可以看到详情

这个方法会遍历池,并且在第一个空闲的存储位置创建任务。如果没有空闲的,就会返回一个空的 SpawnToken, 空的 SpawnToken 会导致 Spawner::spawn() 返回错误。


Try to spawn a task in the pool.

See TaskStorage::spawn() for details.

This will loop over the pool and spawn the task in the first storage that is currently free. If none is free, a “poisoned” SpawnToken is returned, which will cause Spawner::spawn() to return the error.
