Struct MetricsProviderBuilder 

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

Builder with independent pull and push capabilities. No global SDK provider is installed.

Implementations§

Source§

impl MetricsProviderBuilder

Source

pub fn with_limits(self, limits: MetricsLimits) -> Self

Source

pub fn with_resource(self, resource: MetricsResource) -> MetricResult<Self>

Explicit resource attributes only; SDK environment resource detectors are excluded.

§Errors

Returns a redacted error for an empty service name or oversized/control-character attributes.

Source

pub fn with_prometheus(self) -> MetricResult<Self>

§Errors

Returns an error if pull export is already configured or its reader cannot be created.

Source

pub fn with_reader<R: MetricReader>(self, reader: R) -> Self

Reader injection also permits deterministic tests and custom exporters.

Source

pub fn build(self) -> MetricResult<MetricsProvider>

§Errors

Returns an error if the resource limits are invalid.

Source§

impl MetricsProviderBuilder

Source

pub fn with_otlp( self, config: OtlpMetricsConfig, ) -> MetricResult<(Self, OtlpExportDiagnostics)>

The standard SDK owns cumulative aggregation and its one periodic worker. One observation feeds both readers; requests never run in product call paths.

§Errors

Returns a redacted error if configuration is invalid or the HTTP client cannot be created.
