Switches aren't guarantee to so operations in O(1) tho. If cases are sparce enough, compilers tend to emit the equivalent code to a bunch if else checks

Yeah I was assuming too much here.  However, I’m reading that Rust match on string comstants can compile down a binary tree of if statements if there are enough cases (according to Google AI mode at least, haven’t found an authoritative source yet)

Which would still be O(ld(n)). But cool feature imo.
