1680724 - Add a utility function that converts a T* to a Maybe<T&>

Status: RESOLVED FIXED

(Core :: MFBT, task)

Description

[Simon Giesecke [:sg] [he/him]]

It would be convenient to have a utility function that converts a potentially nullptr T* to a Maybe<T&> like:

template<typename T>
Maybe<T&> ToMaybeRef(T* const aPtr) {
  return aPtr ? SomeRef(*aPtr) : Nothing{};
}
