[][src]Struct tokio::runtime::Handle

pub struct Handle { /* fields omitted */ }

Handle to the runtime

Methods

impl Handle[src]

pub fn enter<F, R>(&self, f: F) -> R where
    F: FnOnce() -> R, 
[src]

Enter the runtime context

impl Handle[src]

Important traits for JoinHandle<T>
pub fn spawn<F>(&self, future: F) -> JoinHandle<F::Output> where
    F: Future + Send + 'static,
    F::Output: Send + 'static, 
[src]

Spawn a future onto the Tokio runtime.

This spawns the given future onto the runtime's executor, usually a thread pool. The thread pool is then responsible for polling the future until it completes.

See module level documentation for more details.

Examples

use tokio::runtime::Runtime;

// Create the runtime
let rt = Runtime::new().unwrap();
let handle = rt.handle();

// Spawn a future onto the runtime
handle.spawn(async {
    println!("now running on a worker thread");
});

Panics

This function panics if the spawn fails. Failure occurs if the executor is currently at capacity and is unable to spawn a new future.
