Struct StripRail 

pub struct StripRail {
    pub content: Rect,
    pub count: usize,
    pub focused: usize,
    pub visible: Vec<usize>,
}

A map of the windows along one strip, and where on it the user is standing — the counterpart of StripRibbon for the axis a strip can overflow. Three facts in order of importance: how many windows the strip holds (one segment each — the fact that makes travel worth attempting), which has focus (the long, bright segment), and which are on screen right now (the middle weight, sliding as the strip pans).

A control, not a readout: clicking a segment focuses that window. Bottom edge, because the disc owns the left and the strip ribbon owns the right.

Fields

content: Rect

count: usize

focused: usize

visible: Vec<usize>

Empty before the first layout pass has anything to report.

Implementations

impl StripRail

pub fn is_meaningful(&self) -> bool

One window is not a strip you can travel along, and a single segment would be noise.

pub fn extent(&self) -> f64

pub fn segment_rect(&self, i: usize) -> Option<Rect>

pub fn hit_rect(&self, i: usize) -> Option<Rect>

Widened past the visible segment to the minimum pointer target across the rail’s short axis.

pub fn hit(&self, p: Point) -> Option<usize>

pub fn draw( &self, scene: &mut Scene, transform: Affine, theme: &Theme, hover: Option<usize>, alpha: f32, )

Trait Implementations

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for StripRail

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.
