> Implementing a function that should be called also for null input requires declaring it, by wrapping relevant arguments in Option<...> If we can handle `Option<T>` as `null` and we can define whatever we want for null case then I think it is good enough to land as the first step. We need Option both in `inputs` and `return type` ``` fn concat(a: Option<T>, b: Option<T>) -> Result<Option<T>> ``` -- This is an automated message from the Apache Git Service.
