Trait druid::widget::WidgetWrapper

pub trait WidgetWrapper {
    type Wrapped;

    // Required methods
    fn wrapped(&self) -> &Self::Wrapped;
    fn wrapped_mut(&mut self) -> &mut Self::Wrapped;
}

A trait for widgets that wrap a single child to expose that child for access and mutation

Required Associated Types

type Wrapped

The type of the wrapped widget. Maybe we would like to constrain this to Widget<impl Data> (if existential bounds were supported). Any other scheme leads to T being unconstrained in unification at some point

Required Methods

fn wrapped(&self) -> &Self::Wrapped

Get immutable access to the wrapped child

fn wrapped_mut(&mut self) -> &mut Self::Wrapped

Get mutable access to the wrapped child
