Trait GpuiComponentStateValueBinding 

pub trait GpuiComponentStateValueBinding<Value>: EventEmitter<Self::Event> {
    type Event: 'static;

    // Required method
    fn value_change(state: &Self, event: &Self::Event) -> ValueChange<Value>;

    // Provided method
    fn seed_value_binding_state(
        _state: &mut Self,
        _value: Option<&Value>,
        _window: &mut Window,
        _cx: &mut Context<'_, Self>,
    )
       where Self: Sized { ... }
}

Value-binding contract implemented by backing component state.

Required Associated Types

type Event: 'static

Event emitted by the backing component state.

Required Methods

fn value_change(state: &Self, event: &Self::Event) -> ValueChange<Value>

Convert an emitted component event into a normalized value change.

Provided Methods

fn seed_value_binding_state( _state: &mut Self, _value: Option<&Value>, _window: &mut Window, _cx: &mut Context<'_, Self>, )

where Self: Sized,

Seed component state from the current value.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
