Struct NoopTelemetry 

pub struct NoopTelemetry;

Telemetry implementation that discards all metrics and events.

This is useful in tests and extremely constrained environments where telemetry is not required.

Trait Implementations

impl Clone for NoopTelemetry

fn clone(&self) -> NoopTelemetry

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for NoopTelemetry

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

Formats the value using the given formatter.

impl Default for NoopTelemetry

fn default() -> NoopTelemetry

Returns the “default value” for a type.

impl Telemetry for NoopTelemetry

const METRICS_ENABLED: bool = false

Compile-time flag indicating whether this telemetry implementation wants metrics (counters, gauges, latencies) at all.

const EVENTS_STATICALLY_ENABLED: bool = false

Compile-time flag indicating whether this telemetry implementation ever produces structured events.

fn incr_counter(&mut self, _key: TelemetryKey, _delta: u64)

Increment a counter metric identified by the given key.

fn set_gauge(&mut self, _key: TelemetryKey, _value: u64)

Set a gauge metric identified by the given key.

fn record_latency_ns(&mut self, _key: TelemetryKey, _value_ns: u64)

Record a latency sample in nanoseconds for the given key.

fn push_metrics(&mut self)

Optional: push a snapshot of aggregated metrics to the sink.

fn events_enabled(&self) -> bool

Return true if this telemetry collector wants structured events.

fn push_event(&mut self, _event: TelemetryEvent)

Emit a structured telemetry event.

fn flush(&mut self)

Flush any buffered telemetry data to the underlying sink.
