Struct PhaseRecvStats

    pub fast_catches: u64,

Instrumentation for BlockingSpscRing::recv_phase_locked: how each item was caught. The headline ratio is spin_catches (no wake syscall) vs doorbell_catches (a park/wake round-trip).

Fields

fast_catches: u64

Item already present at entry (no wait at all).

predictive_parks: u64

Predictive parks: a budgeted wait until just before the predicted arrival, in engaged mode.

spin_catches: u64

Item caught by the guard-band spin after a predictive park - the syscall-free path the experiment is about.

doorbell_parks: u64

Doorbell parks: a park in the fallback (disengaged or missed-prediction) path.

doorbell_catches: u64

Item caught in the fallback path.
