Python 2 is no longer supported by the community. We recommend that you migrate Python 2 apps to Python 3.

The RpcStatus Class

The RpcStatus class provides the status of an on-going or complete RPC via the following fields:

state: The State of the RPC.
error_name: The Error name set by the application. Only set when the status is APPLICATION_ERROR. Used by the application to transmit the specific reason for an error.
error_message: The error message associated with the RPC status.

The RpcStatus class provides a subclass, State, an Enum of possible RPC states:

OK: The RPC completed successfully.
RUNNING: The RPC is still running (not complete)
REQUEST_ERROR: The request was malformed or incomplete.
SERVER_ERROR: The server experienced an unexpected error.
NETWORK_ERROR: An error occured in the network.
APPLICATION_ERROR: The application is indicating an error. When in this state, the RPC needs automatically sets application_error.
