Struct Prop 

pub struct Prop<T>(/* private fields */);

A widget property: either a value set once, or a binding that reruns whenever a signal it read changes.

You never build one yourself. Widget methods take impl IntoProp<T>, so .height(30) sets a value and .height(move || ...) makes a binding.

Implementations

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

pub fn shared(self) -> Rc<dyn Fn() -> T>

The property as a closure that can be called again and shared, as a widget built from other widgets hands one property to many of them. A binding stays one: whatever calls it subscribes to the signals it reads.
