Trait MenuListItem

pub trait MenuListItem<R>: Marker + View {
    // Required methods
    fn value_of(&self) -> R;
    fn interact(&mut self) -> R;
    fn set_style(&mut self, text_style: &MonoTextStyle<'_, BinaryColor>);
    fn draw_styled<D>(
        &self,
        text_style: &MonoTextStyle<'static, BinaryColor>,
        display: &mut D,
    ) -> Result<(), D::Error>
       where D: DrawTarget<Color = BinaryColor>;

    // Provided method
    fn selectable(&self) -> bool { ... }
}

Required Methods

fn value_of(&self) -> R

Returns the value of the selected item, without interacting with it.

fn interact(&mut self) -> R

fn set_style(&mut self, text_style: &MonoTextStyle<'_, BinaryColor>)

fn draw_styled<D>( &self, text_style: &MonoTextStyle<'static, BinaryColor>, display: &mut D, ) -> Result<(), D::Error>

where D: DrawTarget<Color = BinaryColor>,

Provided Methods

fn selectable(&self) -> bool

Returns whether the list item is selectable.

If this returns false, the list item will not be interactable and user navigation will skip over it.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
