Struct MetricsProvider 

pub struct MetricsProvider { /* private fields */ }

Clones share one instance; instruments always remain bound to their original instance.

Implementations

impl MetricsProvider

pub fn builder() -> MetricsProviderBuilder

pub fn enabled(&self) -> bool

pub fn otlp_diagnostics(&self) -> Option<OtlpExportDiagnostics>

Returns local push-export diagnostics without invoking the exporter.

pub fn register_batch( &self, descriptors: &[MetricDescriptor], ) -> MetricResult<Vec<MetricHandle>>

Validate the complete batch and reserve every derived exposition name before constructing SDK instruments. Failure leaves this instance unchanged.

Errors

Returns an error for a closed instance, invalid descriptors, duplicate names or instrument limits. The catalog is unchanged on failure.

pub fn descriptors(&self) -> Vec<MetricDescriptor>

pub async fn export_prometheus(&self, timeout: Duration) -> MetricResult<String>

Prometheus export is blocking work with retained concurrency permits. A timed-out caller cannot start unlimited gathers that are still running.

Errors

Returns an error for unavailable or closed providers, concurrent overload, timeout, encoding failure or oversized output.

pub async fn shutdown(&self, timeout: Duration) -> MetricResult<()>

Idempotent shutdown. If the caller times out, the job retains its permit; callers can poll the actual result with shutdown_result.

Errors

Returns an error on concurrent lifecycle operations, timeout or SDK shutdown failure.

pub fn shutdown_result(&self) -> Option<MetricResult<()>>

pub async fn force_flush(&self, timeout: Duration) -> MetricResult<()>

Errors

Returns an error for closed providers, concurrent lifecycle operations, timeout or SDK export failure.

Trait Implementations

impl Clone for MetricsProvider

fn clone(&self) -> MetricsProvider

Returns a duplicate of the value.

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

Performs copy-assignment from source.
