Struct IndicatorArc 

pub struct IndicatorArc { /* private fields */ }

Where the track sits on a display of the given radius.

Implementations

impl IndicatorArc

pub fn centreline(self) -> f32

Radius of the stroke’s centreline.

pub fn width(self) -> f32

Stroke width.

pub fn segment_inset(self) -> f32

Angular amount removed from each segment before its round caps draw.

pub fn start_angle(self) -> f32

The angle at which the track starts, measured the way a canvas measures it: 0 at 3 o’clock, increasing clockwise.

pub fn sweep(self) -> f32

The whole track’s sweep in radians.

pub fn cap_sweep(self) -> f32

How much angle a round cap adds beyond the nominal arc at each end.

Wear draws each segment inset by half a cap at the start and a whole cap shorter, so the round caps put the ink back exactly on the nominal bounds. A caller that draws with a butt cap wants this to be zero.
