Struct ToleranceSpec 

pub struct ToleranceSpec { /* private fields */ }

Declared tolerance for one invariant (R2.3): tolerates N consecutive unhealthy samples and/or unconfirmed for duration D.

There is NO default tolerance — the constructors are the only way to build one, and each requires an explicit declaration. Deserialization re-validates through the same constructors, so a stored record cannot smuggle an undeclared tolerance back in.

Implementations

impl ToleranceSpec

pub const fn count(windows: u64) -> Self

Count form: tolerates windows consecutive unhealthy samples; the (windows + 1)-th consecutive unhealthy sample exceeds tolerance. Zero is a legitimate DECLARED value (alarm on the first unhealthy sample) — what is refused is absence, never zero.

pub const fn duration( unconfirmed_for: Duration, ) -> Result<Self, WorkloopSpecError>

Duration form: alarms once the invariant has gone unconfirmed for unconfirmed_for — the only form evaluable engine-side with zero samples (R2.4a).

Errors

Refuses a zero duration (WorkloopSpecError::ToleranceZeroDuration).

pub const fn both( windows: u64, unconfirmed_for: Duration, ) -> Result<Self, WorkloopSpecError>

Both forms together: the count form may be declared in addition to the duration form, never instead (R2.4a).

Errors

Refuses a zero duration (WorkloopSpecError::ToleranceZeroDuration).

pub const fn consecutive_windows(&self) -> Option<u64>

The declared count form, when present.

pub const fn unconfirmed_for(&self) -> Option<Duration>

The declared duration form, when present.
