Struct Executor

pub struct Executor { /* private fields */ }

A handle through which futures can be executed.

This structure is an instance of a Source which can be used to manage the execution of a number of futures within.

Implementations

impl Executor

pub fn new() -> Self

Creates a new executor unassociated with any context ready to start spawning futures.

pub fn attach(&self, cx: &MainContext)

Attaches this executor to a context, returning the token that it was assigned.

This is required to be called for futures to be completed.

pub fn remote(&self) -> Remote

Generates a remote handle to this event loop which can be used to spawn tasks from other threads into this event loop.

pub fn destroy(&self)

Unregister this executor and free up internal resources.

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

Spawns a new future onto the event loop that this source is associated with.

This function is given a future which is then spawned onto the glib event loop. The glib event loop will listen for incoming events of when futures are ready and attempt to push them all to completion.

The futures spawned here will not be completed unless the attach function is called above.

pub fn spawn_fn<F, R>(&self, f: F)

where F: FnOnce() -> R + 'static, R: IntoFuture<Item = (), Error = ()> + 'static,

Same as spawn above, but spawns a function that returns a future

Trait Implementations

impl Clone for Executor

fn clone(&self) -> Executor

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<F> Executor<F> for Executor

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”.
