Module gauge 

Gauges: ProgressRing (a countdown or progress ring with a centred readout) and BarGauge (a labelled horizontal bar).

The ring sweeps clockwise from 12 o’clock (-π/2) with a round-capped arc over a track that registers against the ground and leaves the fill at least 3:1 against it. Its fill is progress (the inverted fill), a measured level that turns warning and danger past GaugeThresholds, or a Tone. The bar fills a rounded track left to right. Every colour and size comes from the Theme.

Structs

BarGauge

Labelled horizontal bar gauge — a rounded track with a left-anchored fill, a top-left label and a right-aligned value readout.

GaugeReading

What an immediate-mode gauge paints: how full it is, in which colour, and the text around it. Either string may be empty.

GaugeStyle

Paint options of a BarGauge.

GaugeThresholds

Fraction thresholds (inclusive lower bounds) at which a gauge switches from success → warning → danger. The default mirrors the dashboard convention: >= 0.85 danger, >= 0.6 warning, else success.

ProgressRing

A retained progress ring. See ProgressRingFace.

ProgressRingFace

Immediate-mode progress ring: a countdown or progress with an optional centred readout.

RingReading

What a state-bound ring shows (ProgressRing::from_state).

Enums

ProgressRingSize

How large a ProgressRing is. Each size reads from the theme’s metrics, so it follows the UI scale.
