Struct lunatic_runtime::api::process::EXECUTOR

pub struct EXECUTOR { /* fields omitted */ }

Methods from Deref<Target = TaskExecutor<'static>>

pub fn is_empty(&self) -> bool

Returns true if there are no unfinished tasks.

Examples

use async_executor::Executor;

let ex = Executor::new();
assert!(ex.is_empty());

let task = ex.spawn(async {
    println!("Hello world");
});
assert!(!ex.is_empty());

assert!(ex.try_tick());
assert!(ex.is_empty());

pub fn spawn<T>(&self, future: impl Future<Output = T> + Send + 'a) -> Task<T> where
    T: 'a + Send, 

Spawns a task onto the executor.

Examples

use async_executor::Executor;

let ex = Executor::new();

let task = ex.spawn(async {
    println!("Hello world");
});

pub fn try_tick(&self) -> bool

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::Executor;

let ex = Executor::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)

Runs 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::Executor;
use futures_lite::future;

let ex = Executor::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

Runs the executor until the given future completes.

Examples

use async_executor::Executor;
use futures_lite::future;

let ex = Executor::new();

let task = ex.spawn(async { 1 + 2 });
let res = future::block_on(ex.run(async { task.await * 2 }));

assert_eq!(res, 6);
