Struct DriveLoopProfiler 

pub struct DriveLoopProfiler { /* private fields */ }

Owns every drive-loop phase/rate ring drive_runtime_until_shutdown writes into once per iteration. Lives on NodeShared behind a std::sync::Mutex that is only ever locked for a push and dropped before the next .await – never held across one, so it does not need tokio::sync::Mutex.

Implementations

impl DriveLoopProfiler

pub fn record_runtime_tick(&mut self, elapsed: Duration)

runtime.tick().await – the whole native-runtime tick, whose own six internal phases are separately timed by gate4agent_runtime_native::tick_profile.

pub fn record_event_drain(&mut self, elapsed: Duration)

Draining events.try_recv() in a loop and republishing each control event – includes the per-event managed-record export lookup, but not the detached tokio::spawn’d export task itself.

pub fn record_publish_terminal_frames(&mut self, elapsed: Duration)

shared.publish_terminal_frames() – snapshotting sessions, then diffing and broadcasting any advanced terminal frame.

pub fn record_remainder(&mut self, elapsed: Duration)

Whatever is left of the iteration after the three phases above and before the trailing sleep – today that is the shutdown-progress check (a no-op outside shutdown) plus this profiler’s own bookkeeping.

pub fn note_iteration(&mut self, now: Instant)

Call exactly once per drive-loop iteration, regardless of what that iteration did – rolls the current one-second bucket into iterations_per_sec the moment a full second has elapsed, then counts this iteration toward the (possibly just-rolled) bucket. Rolling before counting means an iteration observed after a second boundary is credited to the new second, not folded into the one being flushed.

Bounded to SAMPLE_WINDOW catch-up rolls for the same reason as hatchery-tui’s tick_second: a long idle gap (e.g. the process paused under a debugger) must resync rather than spin backfilling a zero-sample per elapsed second.

pub fn snapshot(&self) -> DriveLoopProfileSnapshot
