Detailed Description

template<typename To, typename From, typename Derived = void>
struct llvm::OptionalValueCast< To, From, Derived >

This cast trait provides std::optional<T> casting.

This means that if you have a value type, you can cast it to another value type and have dyn_cast return an std::optional<T>.
