Rodin::Utility::OptionalReference class

A wrapper providing optional reference semantics.

Template parameters
T	The referenced type.

OptionalReference provides a way to have an optional reference, combining the functionality of std::optional with reference semantics. This is useful when a function may or may not return a reference to an object.

The class inherits from Optional<std::reference_wrapper<T>> and provides convenient pointer-like and reference access operators.

Example usage:

int value = 42;
OptionalReference<int> optRef;  // Empty optional reference
optRef = value;  // Now refers to value

if (optRef)
{
    *optRef = 100;  // Modifies value through the reference
}

Public types
