Struct OneWayBinding 

pub struct OneWayBinding<T: Clone + 'static> { /* private fields */ }

A one-way binding that pushes signal changes to a property sink.

When the source signal changes, the binding reads the new value and calls PropertySink::set_value on the sink.

Examples

let count = Signal::new(0);
let display = Rc::new(RefCell::new(String::new()));

let binding = OneWayBinding::new(&count, {
    let display = display.clone();
    move |v: &i32| *display.borrow_mut() = format!("{v}")
});

count.set(42);
assert_eq!(*display.borrow(), "42");

Implementations

impl<T: Clone + 'static> OneWayBinding<T>

pub fn new(source: &Signal<T>, sink: impl PropertySink<T> + 'static) -> Self

Create a new one-way binding from source to sink.

The sink is called immediately with the current value, and again whenever the source signal changes.
