Rust const fn and C++ constexpr solve a similar problem—allowing computations to happen at compile time—but their design philosophies are quite different.

Debugging할때 나오는 Alingment와 Size 개념을 잡아보자. The reason Vulkan uses optional<uint32_t> here is semantic rather than performance-related: a queue-family index may or may not have been found yet. The optional makes that state explicit instead of inventing a special sentinel integer.

The idea is RAII: acquire the resource in the constructor, and release it in the destructor. With std::unique_ptr or std::shared_ptr, you can instead give the smart pointer a custom deleter that knows how to release a non-C++ resource
