"""Error codes (experimental module).

These types represent a subset of the Google error codes [1], which are
also used by TensorFlow, gRPC, et al.

When an HTTP handler raises one of these errors, the TensorBoard core
application will catch it and automatically serve a properly formatted
response with the error message.
