Struct OriginProbePolicy 

pub struct OriginProbePolicy {
    pub positive_ttl: Duration,
    pub negative_ttl: Duration,
    pub fault_ttl: Duration,
    pub timeout: Duration,
    pub capacity: usize,
}

Live-origin probe policy: the three answer TTLs, the per-probe HEAD ceiling, and the memo’s capacity, resolved from the cache.origin_probe_* knobs.

Passed as one value rather than five positional arguments because four of them are Duration: any transposition of the TTLs and the timeout would compile and pass every test, while quietly changing how long a fault or an absence stands.

Fields

positive_ttl: Duration

TTL for a memoised Present answer (cache.origin_probe_ttl_sec).

negative_ttl: Duration

TTL for a memoised Absent answer (cache.origin_probe_negative_ttl_sec).

fault_ttl: Duration

TTL for a memoised Fault answer (cache.origin_probe_fault_ttl_sec).

timeout: Duration

Per-probe ceiling on the live HEAD/HeadObject (cache.origin_probe_timeout_ms).

capacity: usize

Max distinct hashes held in the memo (cache.origin_probe_memo_capacity).
