Std::result - Rust

Iterating over Result. A Result can be iterated over. This can be helpful if you need an iterator that is conditionally empty. The iterator will either produce a single value (when the Result is Ok), or produce no values (when the Result is Err).For example, into_iter acts like once(v) if the Result is Ok(v), and like empty() if the Result is Err. Iterators over Result<T, E> come in three types:
