Struct AlertWindow 

#[non_exhaustive]
pub struct AlertWindow {
    pub severity: Severity,
    pub long: Window,
    pub short: Window,
    pub factor: f64,
}

One burn-rate condition: a long and short window that must both be burning faster than factor times the budget for the alert to fire.

The struct is #[non_exhaustive] so per-condition options (for example a for duration or per-condition labels) can be added without a breaking change; build values with AlertWindow::new. The fields stay public for reading and mutation.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

severity: Severity

Whether this condition pages or tickets.

long: Window

The long lookback window (e.g. 1h).

short: Window

The short lookback window that confirms the burn is still happening (e.g. 5m).

factor: f64

The burn-rate multiplier that triggers this condition.

Implementations

impl AlertWindow

pub const fn new( severity: Severity, long: Window, short: Window, factor: f64, ) -> Self

Build a burn-rate condition from its severity, lookback windows, and burn-rate factor.

pub fn threshold(&self, slo: &Slo) -> f64

The error-ratio threshold for this condition against slo: factor * (1 - objective).
