[−][src]Struct async_executor::LocalExecutor
A thread-local executor.
The executor can only be run on the thread that created it.
Examples
use async_executor::LocalExecutor; use futures_lite::future; let local_ex = LocalExecutor::new(); future::block_on(local_ex.run(async { println!("Hello world!"); }));
Implementations
impl LocalExecutor
[src]
pub const fn new() -> LocalExecutor
[src]
Creates a single-threaded executor.
Examples
use async_executor::LocalExecutor; let local_ex = LocalExecutor::new();
pub fn spawn<T: 'static>(
&self,
future: impl Future<Output = T> + 'static
) -> Task<T>ⓘ
[src]
&self,
future: impl Future<Output = T> + 'static
) -> Task<T>ⓘ
Spawns a task onto the executor.
Examples
use async_executor::LocalExecutor; let local_ex = LocalExecutor::new(); let task = local_ex.spawn(async { println!("Hello world"); });
pub fn try_tick(&self) -> bool
[src]
Attempts to run a task if at least one is scheduled.
Running a scheduled task means simply polling its future once.
Examples
use async_executor::LocalExecutor; let ex = LocalExecutor::new(); assert!(!ex.try_tick()); // no tasks to run let task = ex.spawn(async { println!("Hello world"); }); assert!(ex.try_tick()); // a task was found
pub async fn tick<'_>(&'_ self)
[src]
Run a single task.
Running a task means simply polling its future once.
If no tasks are scheduled when this method is called, it will wait until one is scheduled.
Examples
use async_executor::LocalExecutor; use futures_lite::future; let ex = LocalExecutor::new(); let task = ex.spawn(async { println!("Hello world"); }); future::block_on(ex.tick()); // runs the task
pub async fn run<T, '_>(&'_ self, future: impl Future<Output = T>) -> T
[src]
Runs the executor until the given future completes.
Examples
use async_executor::LocalExecutor; use futures_lite::future; let local_ex = LocalExecutor::new(); let task = local_ex.spawn(async { 1 + 2 }); let res = future::block_on(local_ex.run(async { task.await * 2 })); assert_eq!(res, 6);
