Struct tokio_core::reactor::Handle

pub struct Handle { /* fields omitted */ }

A non-sendable handle to an event loop, useful for manufacturing instances of LoopData.

Methods

impl Handle

fn remote(&self) -> &Remote

Returns a reference to the underlying remote handle to the event loop.

fn spawn<F>(&self, f: F) where
    F: Future<Item = (), Error = ()> + 'static, 

Spawns a new future on the event loop this handle is associated with.

Panics

This method will not catch panics from polling the future f. If the future panics then it's the responsibility of the caller to catch that panic and handle it as appropriate.

fn spawn_fn<F, R>(&self, f: F) where
    F: FnOnce() -> R + 'static,
    R: IntoFuture<Item = (), Error = ()> + 'static, 

Spawns a closure on this event loop.

This function is a convenience wrapper around the spawn function above for running a closure wrapped in futures::lazy. It will spawn the function f provided onto the event loop, and continue to run the future returned by f on the event loop as well.

Panics

This method will not catch panics from polling the future f. If the future panics then it's the responsibility of the caller to catch that panic and handle it as appropriate.

fn id(&self) -> CoreId

Return the ID of the represented Core

Trait Implementations

impl Clone for Handle

fn clone(&self) -> Handle

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<F> Executor<F> for Handle where
    F: Future<Item = (), Error = ()> + 'static, 

fn execute(&self, future: F) -> Result<(), ExecuteError<F>>

Spawns a future to run on this Executor, typically in the "background".

impl Debug for Handle

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.
