Struct Meter 

pub struct Meter { /* private fields */ }

A load ratio in 0.0..=1.0, mapped to a green→yellow→red color ramp.

Low load is green, mid load yellow, high load red. Values outside the range are clamped. Delegates to Color::lerp (backed by gem) rather than hand-rolling RGB interpolation.

Not a drawing widget – there’s no Terminal involved, just a ratio-to-color mapping – but kept as its own small struct rather than a free function so Gauge, StatBar, and Sparkline share one place that owns the ramp.

Implementations

impl Meter

pub const fn new(ratio: f32) -> Self

A meter reading ratio (clamped to 0.0..=1.0 when colored).

pub fn color(self) -> Color

The ramped color for this meter’s ratio.
