Struct TelemetryHandle 

Source 
pub struct TelemetryHandle { /* private fields */ }
Expand description

Cloneable telemetry capability injected into business components.

This type deliberately has no shutdown method and contains no SDK provider. Clone it freely; the corresponding non-cloneable TelemetryRuntimeGuard remains the sole shutdown owner.

Implementations§

Source§

impl TelemetryHandle

Source

pub const fn noop() -> TelemetryHandle

Creates a handle that never reads or installs OpenTelemetry global state.

Source

pub fn state(&self) -> TelemetryState

Returns the current shared lifecycle state.

Source

pub fn is_active(&self) -> bool

Returns whether this handle currently admits telemetry operations.

Source

pub fn metrics_enabled(&self) -> bool

Returns whether this active runtime currently enables metrics.

Source

pub fn metrics_runtime_policy(&self) -> MetricsRuntimePolicy

Returns final metrics runtime policy while the telemetry lifecycle is active.

No-op, closing, and closed handles return a disabled policy so surviving clones cannot continue metrics work after their runtime owner begins shutdown.

Source

pub fn trace_policy(&self) -> TracePolicy

Returns this handle’s immutable trace policy while the runtime is active.

A closing or closed handle returns a disabled policy so clones that outlive their runtime cannot continue producing telemetry.

Source

pub fn metric_label_policy(&self) -> MetricLabelPolicy

Returns this telemetry instance’s shared metric-label policy.

Clones of this handle share one bounded-cardinality budget. Independently initialized handles receive independent policies and budgets.

Source

pub fn child(&self, scope: &'static str) -> TelemetryRecorder

Returns a recorder bound to a fixed instrumentation scope.

Source

pub fn release_identity_registered(&self) -> bool

Returns whether this active runtime registered a release identity.
