Hi all, Does using Option incur a runtime cost (like increased memory usage) compared to a hypothetical case if Rust had a NULL type in the language? Or does it get optimized away, such that it is akin to using NULL in the first place (albeit safer of course)?
I have not looked at any assemblies, ut my intuition says that a comparison with None is a single-word check, so it should be pretty fast. Thanks -- Ziad
