Struct LoggerProviderBuilder 

pub struct LoggerProviderBuilder { /* private fields */ }

Builder for provider attributes.

Implementations

impl LoggerProviderBuilder

pub fn with_simple_exporter<T: LogExporter + 'static>(self, exporter: T) -> Self

Adds a SimpleLogProcessor with the configured exporter to the pipeline.

Arguments

• exporter - The exporter to be used by the SimpleLogProcessor.

Returns

A new Builder instance with the SimpleLogProcessor added to the pipeline.

Processors are invoked in the order they are added.

pub fn with_batch_exporter<T: LogExporter + 'static>(self, exporter: T) -> Self

Adds a BatchLogProcessor with the configured exporter to the pipeline, using the default super::BatchConfig.

The following environment variables can be used to configure the batching configuration:

• OTEL_BLRP_SCHEDULE_DELAY - Corresponds to with_scheduled_delay.
• OTEL_BLRP_MAX_QUEUE_SIZE - Corresponds to with_max_queue_size.
• OTEL_BLRP_MAX_EXPORT_BATCH_SIZE - Corresponds to with_max_export_batch_size.

Arguments

• exporter - The exporter to be used by the BatchLogProcessor.

Returns

A new LoggerProviderBuilder instance with the BatchLogProcessor added to the pipeline.

Processors are invoked in the order they are added.

pub fn with_log_processor<T: LogProcessor + 'static>(self, processor: T) -> Self

Adds a custom LogProcessor to the pipeline.

Arguments

• processor - The LogProcessor to be added.

Returns

A new Builder instance with the custom LogProcessor added to the pipeline.

Processors are invoked in the order they are added.

pub fn with_resource(self, resource: Resource) -> Self

Associates a Resource with a SdkLoggerProvider.

This Resource represents the entity producing telemetry and is associated with all Loggers the SdkLoggerProvider will create.

By default, if this option is not used, the default Resource will be used.

When constructing a Resource, use Resource::builder() to preserve SDK-provided defaults such as telemetry.sdk.* and service.name. Using Resource::builder_empty() will not include these attributes.

Example

use opentelemetry_sdk::{Resource, logs::SdkLoggerProvider};
use opentelemetry::KeyValue;

let provider = SdkLoggerProvider::builder()
    .with_resource(
        Resource::builder()
            .with_service_name("my-service")
            .with_attributes([KeyValue::new("deployment.environment.name", "production")])
            .build(),
    )
    .build();

Note: Calls to this method are additive, each call merges the provided resource with the previous one.

pub fn build(self) -> SdkLoggerProvider

Create a new provider from this configuration.
