Detailed Description

template<typename T>
struct OptionalRef< T >

Wrapper around std::optional<std::reference_wrapper<T>> that provides a more convenient API.

This class provides a convenient wrapper around std::optional<std::reference_wrapper<T>> that allows you to easily access the underlying value without having to check for the presence of a value first.

The operator*() and value() methods return a reference to the underlying value, and the has_value() method can be used to check if a value is present.
