If the type of the result of a call to `IntoIterator::into_iter()` and the type of the receiver are the same, then the receiver implements `Iterator` and `into_iter()` is the identity function. The call to `into_iter()` may be removed in all but two cases: - If the receiver implements `Copy`, `into_iter()` will produce a copy of the receiver and cannot be removed. For example, `x.into_iter().next()` will not advance `x` while `x.next()` will. - If the receiver is an immutable local variable and the call to `into_iter()` appears in a larger expression, removing the call to `into_iter()` might cause mutability issues. For example, if `x` is an immutable local variable, `x.into_iter().next()` will compile while `x.next()` will not as `next()` receives `&mut self`. |
