+/// A ClientContext allows the person implementing a service client to:
+///
+/// - Add custom metadata key-value pairs that will propagated to the server
+/// side.
+/// - Control call settings such as compression and authentication.
+/// - Initial and trailing metadata coming from the server.
+/// - Get performance metrics (ie, census).
+///
+/// Context settings are only relevant to the call they are invoked with, that
+/// is to say, they aren't sticky. Some of these settings, such as the
+/// compression options, can be made persistant at channel construction time
+/// (see \a grpc::CreateCustomChannel).
+///
+/// \warning ClientContext instances should \em not be reused across rpcs.
