nit: I think we usually don't end the developer-readable error messages with a
'.' character.

Done.

Do you want to have a default case that also does
SetError(kErrorPingNotImplemented)?

[Bei Zhang, 2013/06/21 08:31:07]

default case for enums are not recommended as it makes it hard to locate a
missing case. We have an automatic tool to check if all the cases are covered.
