Struct mesh_worker::WorkerHandle

pub struct WorkerHandle { /* private fields */ }

Represents a running Worker instance providing the ability to restart, stop or wait for exit. To launch a worker and get a handle, use WorkerHost::launch_worker

Implementations

impl WorkerHandle

pub fn stop(&mut self)

Requests that the worker stop.

pub async fn join(&mut self) -> Result<()>

Waits until the worker has stopped.

pub fn restart(&mut self, host: &WorkerHost)

Stops the worker, then restarts it, using the same state, on host.

This can be used to upgrade a worker at runtime if host is a worker host in a new process.

Trait Implementations

impl Debug for WorkerHandle

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

Formats the value using the given formatter.

impl DefaultEncoding for WorkerHandle

type Encoding = TableEncoder

The encoding to use for the serialization.

impl FusedStream for WorkerHandle

fn is_terminated(&self) -> bool

Returns true if the stream should no longer be polled.

impl Inspect for WorkerHandle

fn inspect(&self, req: Request<'_>)

Inspects the object.

impl Stream for WorkerHandle

type Item = WorkerEvent

Values yielded by the stream.

fn poll_next( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<Option<Self::Item>>

Attempt to pull out the next value of this stream, registering the current task for wakeup if the value is not yet available, and returning None if the stream is exhausted.

fn size_hint(&self) -> (usize, Option<usize>)

Returns the bounds on the remaining length of the stream.
