Enum IndicatorSegment 

pub enum IndicatorSegment {
    Arc {
        start: f32,
        sweep: f32,
        alpha: f32,
    },
    Dot {
        angle: f32,
        radius: f32,
        alpha: f32,
    },
}

One piece of the indicator, ready to draw.

A segment shorter than its own stroke cannot be drawn as an arc without looking like a blob, so Wear swaps it for a circle that shrinks and fades out together. Callers draw whichever variant they are handed.

Variants

Arc

A stroked arc with a round cap, already inset so the caps land on the nominal bounds. start and sweep are radians, 0 at 3 o’clock.

Fields

start: f32

sweep: f32

alpha: f32

Dot

A filled circle standing in for an arc too short to draw.

Fields

angle: f32

Angle of the dot’s centre, radians.

radius: f32

Radius, in the same unit as the arc’s stroke width.

alpha: f32
