Struct InMemoryLogExporter

pub struct InMemoryLogExporter { /* private fields */ }

An in-memory logs exporter that stores logs data in memory..

This exporter is useful for testing and debugging purposes. It stores logs in a Vec<OwnedLogData>. Logs can be retrieved using get_emitted_logs method.

Example

   // Create an InMemoryLogExporter
   let exporter: InMemoryLogExporter = InMemoryLogExporter::default();
   //Create a LoggerProvider and register the exporter
   let logger_provider = SdkLoggerProvider::builder()
       .with_log_processor(BatchLogProcessor::builder(exporter.clone()).build())
       .build();
   // Setup Log Appenders and emit logs. (Not shown here)
   logger_provider.force_flush();
   let emitted_logs = exporter.get_emitted_logs().unwrap();
   for log in emitted_logs {
       println!("{:?}", log);
   }

Implementations

impl InMemoryLogExporter

pub fn is_shutdown_called(&self) -> bool

Returns true if shutdown was called.

pub fn get_emitted_logs( &self, ) -> Result<Vec<LogDataWithResource>, InMemoryExporterError>

Returns the logs emitted via Logger as a vector of LogDataWithResource.

Example

use opentelemetry_sdk::logs::{InMemoryLogExporter, InMemoryLogExporterBuilder};

let exporter = InMemoryLogExporterBuilder::default().build();
let emitted_logs = exporter.get_emitted_logs().unwrap();

pub fn reset(&self)

Clears the internal (in-memory) storage of logs.

Example

use opentelemetry_sdk::logs::{InMemoryLogExporter, InMemoryLogExporterBuilder};

let exporter = InMemoryLogExporterBuilder::default().build();
exporter.reset();
