Functions

func Code

func Code(err error) codes.Code

Code returns the error code for `err` if it was produced by Venue. Otherwise, it returns codes.Unknown.

func ErrorDesc

	glog.Info(FnName())
}

func FnNameWithArgs

func FnNameWithArgs(args ...string) string

FnNameWithArgs returns the calling function name, with argument values, e.g. "SomeFunction(arg1, arg2)". This is useful for logging function calls with glog.
