Struct Binding 

pub struct Binding<T: 'static> {
    pub read: ReadSignal<T>,
    /* private fields */
}

A reactive, two-way binding to one field-shaped value.

Equality compares the binding’s producer-defined identity. Equal bindings are guaranteed to represent the same read and write behavior; producers may conservatively return unequal bindings when they cannot prove that interchangeability.

Fields

read: ReadSignal<T>

The binding’s reactive value.

Implementations

impl<T: 'static> Binding<T>

pub fn new( read: ReadSignal<T>, write: Callback<(T, ChangeOrigin)>, commit: Callback<()>, ) -> Self

Creates a binding identified by its exact read, write, and commit handles.

pub fn new_with_identity<I>( read: ReadSignal<T>, write: Callback<(T, ChangeOrigin)>, commit: Callback<()>, identity: I, ) -> Self

where I: PartialEq + 'static,

Creates a binding with a producer-defined comparable identity.

Equal identities must always represent interchangeable read, write, and commit behavior. Producers that cannot prove interchangeability should use Binding::new instead.

pub fn write(&self, value: T, origin: ChangeOrigin)

Writes a value and preserves where the change originated.

pub fn commit(&self)

Reports the widget-defined end of one interaction unit.

pub fn into_trio(self) -> BindingPropTrio<T>

Decomposes this binding into the dependency-free widget prop contract.

The lower-level on_change callback has no origin parameter, so its writes are user writes.

Trait Implementations
