Struct TemperatureReading 

pub struct TemperatureReading {
    pub label: Box<str>,
    pub celsius: f32,
    pub peak_celsius: Option<f32>,
    pub critical_celsius: Option<f32>,
}

One temperature sensor reading.

Fields

label: Box<str>

Sensor label, e.g. coretemp Package id 0.

celsius: f32

Current temperature in degrees Celsius.

peak_celsius: Option<f32>

The highest value this sensor has been seen at, where the platform offers one.

Not a threshold, and deliberately not named like one. The underlying interface reports either the sensor’s declared high limit or the maximum value observed since the process started, depending on the platform and the driver, and the two are indistinguishable from here. It is therefore useful as context — “it has been this hot” — and never usable as a full scale for a bar or a percentage. Only TemperatureReading::critical_celsius is a declared ceiling.

critical_celsius: Option<f32>

The critical threshold the sensor reports, where available.

The one figure here that is a genuine ceiling, which is why it is the only denominator anything is allowed to draw a scale against.

Implementations

impl TemperatureReading

pub fn is_critical(&self) -> Option<bool>

Whether the reading is at or above the sensor’s own critical threshold.

Returns None when the sensor reports no threshold. §11.3 forbids diagnosing thermal throttling from an ambiguous metric, so this only ever reports what the sensor itself declares critical, and the diagnostic engine draws no throttling conclusion from it.

pub fn share_of_critical(&self) -> Option<Percent>

The reading as a share of the sensor’s own declared ceiling.

None when the sensor declares none, which is what stops a caller drawing a bar: a temperature has no natural full scale, and 62 °C is most of the way to a laptop’s limit while being barely warm for a GPU. Deliberately refuses TemperatureReading::peak_celsius as a substitute — a bar scaled against the highest value seen so far would sit at 100% forever.

Lives here rather than in the UI so the refusal is the model’s, and every screen that wants a thermal bar gets the same answer (§7.4’s rule about utilization without a known capacity, applied to temperature).
