warning

Documentation

Overview

Package warning communicates warnings over gRPC headers. The Add func is used by the server to add a warning header. The client interceptors log warnings to the logger in the context, or to the default logger.

Note that headers are currently not supported by ServeHTTP of the gRPC server. This means that warnings may not be received by clients using the fallback server.
