Struct gloo_worker::WorkerLink

pub struct WorkerLink<W: Worker> { /* fields omitted */ }

Link to worker’s scope for creating callbacks.

Implementations

impl<W: Worker> WorkerLink<W>

pub fn respond(&self, id: HandlerId, output: W::Output)

Send response to an worker.

pub fn send_message<T>(&self, msg: T) where
    T: Into<W::Message>, 

Send a message to the worker

pub fn send_input<T>(&self, input: T) where
    T: Into<W::Input>, 

Send an input to self

pub fn callback<F, IN, M>(&self, function: F) -> Rc<dyn Fn(IN)> where
    M: Into<W::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::Message>,
    FU: Future<Output = M> + 'static,
    FN: Fn(IN) -> FU + 'static, 

This is supported on crate feature futures only.

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::Message>,
    F: Future<Output = M> + 'static, 

This is supported on crate feature futures only.

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.
