Trait GpuiComponentValueBinding 

pub trait GpuiComponentValueBinding<Value>: GpuiComponentShape
where
    Self::State: EventEmitter<Self::Event>,
{
    type Event: 'static;

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

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

Optional value-binding contract for GPUI component shapes.

Required Associated Types

type Event: 'static

Event emitted by the component state.

Required Methods

fn value_change(state: &Self::State, 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::State, _value: Option<&Value>, _window: &mut Window, _cx: &mut Context<'_, Self::State>, )

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".
