Is there a good way of moving a captured variable out of a closure without cloning it? I have a situation similar to this:

let mut partial_result = String::new();
let mut final_results = vec![];

// Some iterator on which 'for_each' is called
(0..15).for_each(|_| {
    partial_result.push('a'); // builds the partial result further
    if partial_result.len() > 5 { // condition for when the partial result is done
        // save and reset partial_result
        final_results.push(partial_result)
        partial_result = String::new();
    }
});
println!("Result: {final_results:?}");

However as is this causes an error. I would like final_results to take over ownership of the current value in partial_result and then reset partial_result back to it's starting value. In this simple example it can be solved by calling .clone() on partial_result before pushing it. However in the actual code I have some structs which don't necessarily implement Clone<T> so I was wondering if there is some clever way of moving the current value and then immediately resting it to a fixed value in Rust or if I have to make partial_result clonable?
