Async component

Zero overhead reactive programming

Example

See async_component/examples/example.rs for simple example.

See examples/gui-demo project for example using with gui(winit, raqote, pixels).

Code

```Rust use async_component::AsyncComponent;

[derive(Debug, AsyncComponent)]

struct CounterComponent { // State must be wrapped with StateCell #[state(Self::oncounterupdate)] counter: StateCell,

// Stream
// It iterates every queued items in single poll to prevent slowdown.
// If the stream is immediate and resolves indefinitely, the task will fall to infinite loop. See expanded code below.
#[state(Self::on_counter_recv)]
counter_recv: StreamCell<Receiver<i32>>,

}

impl CounterComponent { fn oncounterupdate(&mut self, _: ()) { println!("Counter updated to: {}", *self.counter); }

fn on_counter_recv(&mut self, counter: i32) {
    *self.sub_component.counter = counter;
}

} ```

Running this component stream will print initial value first and print changed value if new values are sent through channel. Counter updated to: 0 Counter updated to: ...
