Struct WorkerScope

pub struct WorkerScope<W>
where
    W: Worker,
{ /* private fields */ }

This struct holds a reference to a component and to a global scheduler.

Implementations

impl<W> WorkerScope<W>

where W: Worker + 'static,

pub fn respond(&self, id: HandlerId, output: <W as Worker>::Output)

Send response to a worker bridge.

pub fn send_message<T>(&self, msg: T)

where T: Into<<W as Worker>::Message>,

Send a message to the worker

pub fn callback<F, IN, M>(&self, function: F) -> Rc<dyn Fn(IN)>

where M: Into<<W as Worker>::Message>, F: Fn(IN) -> M + 'static,

Create a callback which will send a message to the worker when invoked.

pub fn callback_future<FN, FU, IN, M>(&self, function: FN) -> Rc<dyn Fn(IN)>

where M: Into<<W as Worker>::Message>, FU: Future<Output = M> + 'static, FN: Fn(IN) -> FU + 'static,

This method creates a callback which returns a Future which returns a message to be sent back to the worker

Panics

If the future panics, then the promise will not resolve, and will leak.

pub fn send_future<F, M>(&self, future: F)

where M: Into<<W as Worker>::Message>, F: Future<Output = M> + 'static,

This method processes a Future that returns a message and sends it back to the worker.

Panics

If the future panics, then the promise will not resolve, and will leak.
