Required Methods

fn bounds_of(&self, nth: usize) -> Rectangle

fn value_of(&self, nth: usize) -> R

fn interact_with(&mut self, nth: usize) -> R

fn selectable(&self, nth: usize) -> bool

Whether an item is selectable. If not, the item will be skipped.

fn count(&self) -> usize

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

where D: DrawTarget<Color = BinaryColor>,

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.
