pub struct WorkerHandle<W: Component> { /* private fields */ }

Handle to a worker task in the background

Implementations

impl<W: Component> WorkerHandle<W>

where W::Input: 'static, W::Output: 'static,

pub fn connect_receiver<F: FnMut(&mut Sender<W::Input>, W::Output) + 'static>( self, func: F, ) -> WorkerController<W>

Given a mutable closure, captures the receiver for handling.

pub fn forward<X: 'static, F: Fn(W::Output) -> X + 'static>( self, sender: &Sender<X>, transform: F, ) -> WorkerController<W>

Forwards output events to the designated sender.

        };

        let widgets = view_output!();

        ComponentParts { model, widgets }
    }

pub fn detach(self) -> WorkerController<W>

Ignore outputs from the component and finish the builder.
