Worker

Struct Worker 

Source
pub struct Worker<T> { /* private fields */ }
Expand description

Server worker.

A worker runs one service instance on its own arbiter thread. It receives items through an unbounded channel. Clones refer to the same worker.

Implementations§

Source§

impl<T> Worker<T>

Source

pub fn start<F>(name: String, cfg: F, cid: Option<CoreId>) -> Worker<T>
where T: Send + 'static, F: ServerConfiguration<Item = T>,

Starts a worker on a new arbiter thread.

Returns immediately. The worker reports Unavailable until its service is created. If cid is set, the worker thread is pinned to that core.

Source

pub fn name(&self) -> &str

Returns the worker name.

Source

pub fn send(&self, msg: T) -> Result<(), T>

Sends a message to the worker.

Returns Ok if the message was queued. The message is queued even if the worker is currently unavailable. Returns the message as Err if the worker has stopped.

Source

pub fn status(&self) -> WorkerStatus

Returns the current worker status.

Source

pub async fn wait_for_status(&mut self) -> WorkerStatus

Waits for the next worker status change and returns the new status.

Returns immediately if the worker has failed.

Source

pub fn stop(&self, timeout: Millis) -> WorkerStop ⓘ

Stops the worker.

The worker stops accepting items and shuts down its service, waiting up to timeout. A zero timeout uses the default of 3 seconds.
