Struct opentelemetry::sdk::trace::SimpleSpanProcessor [−][src]
pub struct SimpleSpanProcessor { /* fields omitted */ }
trace
only.Expand description
A SpanProcessor
that exports synchronously when spans are finished.
Examples
Note that the simple processor exports synchronously every time a span is ended. If you find this limiting, consider the batch processor instead.
use opentelemetry::{trace::noop::NoopSpanExporter, sdk, global}; // Configure your preferred exporter let exporter = NoopSpanExporter::new(); // Then use the `with_simple_exporter` method to have the provider export when spans finish. let provider = sdk::trace::TracerProvider::builder() .with_simple_exporter(exporter) .build(); let previous_provider = global::set_tracer_provider(provider);
Trait Implementations
on_start
is called when a Span
is started. This method is called
synchronously on the thread that started the span, therefore it should
not block or throw exceptions. Read more
on_end
is called after a Span
is ended (i.e., the end timestamp is
already set). This method is called synchronously within the Span::end
API, therefore it should not block or throw an exception. Read more
Force the spans lying in the cache to be exported.
Shuts down the processor. Called when SDK is shut down. This is an opportunity for processors to do any cleanup required. Read more
