# opentelemetry-stackdriver [Documentation](https://docs.rs/opentelemetry-stackdriver/) This crate provides an `opentelemetry` exporter for use with Google StackDriver trace. It uses gRPC to send tracing spans. It is licensed under the Apache 2.0 license. Contributions are welcome. ## Propagator Feature flag `propagator` will enable the `GoogleTraceContextPropagator` which implements the `TextMapPropagator` trait for Google `X-Cloud-Trace-Context` Trace Context format. Example usage: ```rust opentelemetry::global::set_text_map_propagator(GoogleTraceContextPropagator::new()); ```
