OptTDoIfNone Method

Runs actionOnNone() only if IsNone; and returns itself back. Counterpart of Do(ActionT) for the None variant.

C#

// the logging call will only be made if the result of GetOptionalUser is None.
// Since DoIfNone returns back the option, it can still be assigned to var 'user'.
Opt<User> user = GetOptionalUser().DoIfNone(() => Log.Warning("User could not be read"));
