Expand description

The interface for plugging into a SdkLogger.

Required Methods§

Source

fn emit(&self, data: &mut SdkLogRecord, instrumentation: &InstrumentationScope)

Called when a log record is ready to processed and exported.

This method receives a mutable reference to LogRecord. If the processor needs to handle the export asynchronously, it should clone the data to ensure it can be safely processed without lifetime issues. Any changes made to the log data in this method will be reflected in the next log processor in the chain.

§Parameters

record: A mutable reference to LogRecord representing the log record.
instrumentation: The instrumentation scope associated with the log record.

Source

fn force_flush(&self) -> OTelSdkResult

Force the logs lying in the cache to be exported.

Provided Methods§

Source

fn shutdown_with_timeout(&self, _timeout: Duration) -> OTelSdkResult

Shuts down the processor. After shutdown returns the log processor should stop processing any logs. It’s up to the implementation on when to drop the LogProcessor.
