RPC request metadata.
Once a RPC completes the underlying transport (gRPC or HTTP) may make some metadata attributes about the request available. For the moment we just capture headers, trailers, and tunnel some low-level socket information as fake headers.
Note: When available to applications this information is intended only for debugging and troubleshooting. There is no guarantee that the header names will always be available, or remain stable.Except as otherwise noted, the content of this page is licensed under the Creative Commons Attribution 4.0 License, and code samples are licensed under the Apache 2.0 License.
