Detailed Description

template<typename To, typename From>
struct llvm::CastInfo< To, std::optional< From > >

Provide a CastInfo specialized for std::optional<From>.

It's assumed that if the input is std::optional<From> that the output can be std::optional<To>. If that's not the case, specialize CastInfo for your use case.
