예문을Integer먼저 넣고 두번째 변수는 String 이게 더 좋지 않을까요? 출처 https://www.reddit.com/r/rust/comments/up1yhg/rust_ownership_for_integer_vs_string_literals/What’s going on under the covers is that when a variable who’s type has a constant length (like an integer) gets passed to a function, rust allocates space on the call stack for that variable and copies it’s value into the function’s call stack. Thus the instance of X that your function gets is different (is at a different memory address) than the copy of X that was passed to it. For strings, the compiler doesn’t know how much space to allocate (because the function could be called with your constant length string or any other string).
