Calling this method on None is undefined behavior. Luckily, the as_ref() method of Option allows us to borrow a reference to the contained value: Instead of first using map() to transform to another Option and then unwrapping it, we can use the convenience Lets say youre writing a function that returns a Result because it could fail, and youre calling another function that returns a Result because it could fail. This is achieved with the Option type. Notice the sk.0 since you are using a struct of a tuple type. recommendation please refer to the section on Common Message Since Rust 1.40, you can use Option::as_deref / Option::as_deref_mut: Since Option and Result are so similar, theres an easy way to go between the two.
