Struct OtlpProvider 

pub struct OtlpProvider { /* private fields */ }

Manages the OpenTelemetry SdkLoggerProvider for OTLP export.

Create via OtlpProvider::new, then call OtlpProvider::layer to obtain a tracing_subscriber::Layer that can be composed into the subscriber stack.

The provider must be shut down gracefully via OtlpProvider::shutdown (or by dropping the crate::LoggingGuard) to flush pending log records.

Implementations

impl OtlpProvider

pub fn new( cfg: &OtlpConfig, service_name: &str, environment: &str, version: &str, ) -> LoggingResult<Option<Self>>

Create a new OTLP provider.

Returns Ok(None) when cfg.enabled is false.

pub fn layer<S>( &self, ) -> OpenTelemetryTracingBridge<SdkLoggerProvider, SdkLogger>

where S: Subscriber + for<'a> LookupSpan<'a>,

Get the OpenTelemetry tracing layer for use with tracing_subscriber.

The returned layer converts every tracing event into an OpenTelemetry log record and forwards it to the OTLP exporter.

pub fn shutdown(self) -> LoggingResult<()>

Gracefully shut down the provider, flushing all pending log records.
