Struct Handle

pub struct Handle { /* private fields */ }

A handle to a Runtime that allows spawning additional futures from other threads.

Implementations

impl Handle

pub fn spawn<F>(&self, future: F) -> Result<&Self, SpawnError>

where F: Future<Item = (), Error = ()> + Send + 'static,

Spawn a future onto a runtime in the pool.

This spawns the given future onto a single thread runtime’s executor. That thread is then responsible for polling the future until it completes.

pub fn spawn_all<S>( &self, stream: S, ) -> impl Future<Item = (), Error = StreamSpawnError<<S as Stream>::Error>>

where S: Stream, <S as Stream>::Item: Future<Item = (), Error = ()> + Send + 'static,

Spawn all futures yielded by a stream onto the pool.

This produces a future that accepts futures from a Stream and spawns them all onto the pool round-robin.

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 Debug for Handle

fn fmt(&self, fmt: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Executor for Handle

fn spawn( &mut self, future: Box<dyn Future<Item = (), Error = ()> + Send + 'static>, ) -> Result<(), SpawnError>

Spawns a future object to run on this executor.

fn status(&self) -> Result<(), SpawnError>

Provides a best effort hint to whether or not spawn will succeed.
