# Google Cloud Client Libraries for Rust - Stackdriver Trace API
**FEEDBACK WANTED:** We believe the APIs in this crate are stable, and
do not anticipate any breaking changes are needed. We are looking for
feedback before labeling the APIs "1.0". Changes (even breaking changes)
are still possible, but not expected.
We also believe the implementation is ready for production, bugs are
still possible, but not expected.
Sends application trace data to Stackdriver Trace for viewing. Trace data
is collected for all App Engine applications by default. Trace data from
other applications can be provided using this API. This library is used to
interact with the Trace API directly. If you are looking to instrument
your application for Stackdriver Trace, we recommend using OpenTelemetry.
## Quickstart
