Type Alias Executor

pub type Executor = ThreadPool;

Available on non-WebAssembly and crate feature thread-pool only.

A thread pool executor for futures.

Aliased Type

pub struct Executor { /* private fields */ }

Implementations

impl ThreadPool

pub fn new() -> Result<ThreadPool, Error>

Creates a new thread pool with the default configuration.

See documentation for the methods in ThreadPoolBuilder for details on the default configuration.

pub fn builder() -> ThreadPoolBuilder

Create a default thread pool configuration, which can then be customized.

See documentation for the methods in ThreadPoolBuilder for details on the default configuration.

pub fn spawn_obj_ok(&self, future: FutureObj<'static, ()>)

Spawns a future that will be run to completion.

Note: This method is similar to Spawn::spawn_obj, except that it is guaranteed to always succeed.

pub fn spawn_ok<Fut>(&self, future: Fut)

where Fut: Future<Output = ()> + Send + 'static,

Spawns a task that polls the given future with output () to completion.

use futures::executor::ThreadPool;

let pool = ThreadPool::new().unwrap();

let future = async { /* ... */ };
pool.spawn_ok(future);

Note: This method is similar to SpawnExt::spawn, except that it is guaranteed to always succeed.
