Does not trigger if the function is being exported, -because that might induce API breakage, if the parameter is declared as mutable, -or if the argument is a `self`. - -### Why is this bad? -Arguments passed by value might result in an unnecessary -shallow copy, taking up more space in the stack and requiring a call to -`memcpy`, which can be expensive. - -### Example -``` -#[derive(Clone, Copy)] -struct TooLarge([u8; 2048]); - -fn foo(v: TooLarge) {} -``` - -Use instead: -``` -fn foo(v: &TooLarge) {} -```
