Struct HealthState 

pub struct HealthState { /* private fields */ }

Shared health state, updated by the pipeline runtime and read by the probes. All methods are lock-free and callable from any thread.

Implementations

impl HealthState

pub fn new( pipeline_threads: usize, thresholds: HealthThresholds, ) -> Arc<HealthState>

Create state for pipeline_threads heartbeating threads. All heartbeats start “fresh” at creation time.

pub fn heartbeat(&self, thread: usize)

Beat thread thread’s heart. Called once per poll iteration; out of range indices are ignored (defensive — sizing is fixed at startup).

pub fn set_assignment_received(&self, received: bool)

Mark whether the source has received its (initial) assignment.

pub fn set_sinks_connected(&self, connected: bool)

Mark whether all sinks report connectivity.

pub fn report_watermark(&self, age: Duration, data_flowing: bool)

Report the checkpointer’s oldest-unacknowledged-batch age and whether data is currently flowing (a stuck watermark only counts against liveness while records move).

pub fn ready(&self) -> bool

Readiness: assignment received and sinks connected.

pub fn healthy(&self) -> bool

Liveness now.

pub fn healthy_at(&self, now: Instant) -> bool

Liveness as of now (injectable for tests).

Trait Implementations

impl Debug for HealthState

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.
