Removing redundant clone()

[xdb64]

Lint name: clippy::redundant-clone

I tried this code:

    state
        .query
        .clone()
        .chars()
        .for_each(|_| user_interface.move_cursor(&mut state, Direction::Forward));

Removing clone() from this causes:

error[E0502]: cannot borrow `state` as mutable because it is also borrowed as immutable
