pub struct Value<A> where
A: Display + PartialEq + Debug + Clone, {
pub value: A,
pub signal: Option<Signal2<A, A>>,
}
Expand description
Wraps a single value, notifying listeners when the value changes.
Fields
value: A
signal: Option<Signal2<A, A>>
Implementations

A: Display + PartialEq + Debug + Clone,
impl<A> Value<A> where
A: Display + PartialEq + Debug + Clone,
pub fn new(value: A, listener: Option<Listener2<A, A>>) -> Self
sourcepub fn watch(&mut self, listener: Listener2<A, A>) -> Option<impl Disposable>
pub fn watch(&mut self, listener: Listener2<A, A>) -> Option<impl Disposable>
Immediately calls a listener with the current value, and again whenever the value changes. @returns A handle that can be disposed to stop watching for changes.

pub fn set(&mut self, new_value: A)
pub fn changed(&mut self) -> Option<Signal2<A, A>>
