Thank you, Indeed it seems to be the case that it is more like IsFailed() instead of IsCanceled().
If i examine the *grpc_call* <https://github.com/grpc/grpc/blob/f3b28b81cf5825ce41cbfdf1a926972227034d91/src/core/lib/surface/call.cc#L205> struct, (accessible through the c++ API <https://grpc.io/grpc/cpp/classgrpc_1_1_server_context.html#ac23879ea6fee39bbe27c6b6192989d61>, but using it will require including non-public core lib headers? Which i do not want to do.) it has an *grpc_call_final_info* member defined here <https://github.com/grpc/grpc/blob/dc46c7f565196d6684d5cf6ee81e99b413ba5282/src/core/lib/channel/channel_stack.h#L86> . Which includes a *grpc_status_code* and error message, I do not know if these are set on the server side, but this might be something to expose on the C/C++ API?
