Struct Slider 

pub struct Slider<'a, T = usize>
where
    T: RangeOp<Step: Copy + Debug> + MapRange<u16> + Debug + Default + Copy + PartialEq,
    u16: MapRange<T>,
{ /* private fields */ }

Slider widget for a type T.

T has to implement RangeOp and MapRange to and from u16.

impl<'a, T> StatefulWidget for &Slider<'a, T>

where T: RangeOp<Step: Copy + Debug> + MapRange<u16> + Debug + Default + Copy + PartialEq, u16: MapRange<T>,

type State = SliderState<T>

State associated with the stateful widget.

fn render(self, area: Rect, buf: &mut Buffer, state: &mut Self::State)
