The RpcStatus Class

Experimental!

ProtoRPC is an experimental, innovative, and rapidly changing new feature for App Engine. Unfortunately, being on the bleeding edge means that we may make backwards-incompatible changes to ProtoRPC. We will inform the community when this feature is no longer experimental.

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.
