How can I use a mutable reference mutably after using .iter()?

[twin spade]

    pub fn cleanup(&mut self) {
        for (index, descriptor) in self.descriptors.iter().enumerate() {
            if descriptor.default_axis_value == 0. && descriptor.axis.press.released() {
                self.descriptors.remove(index);
            }
        }
    }

I'm getting a message that I can't use self as mutable again

"Immutable borrows occurs here" is pointing to the iter call

cannot borrow `self.descriptors` as mutable because it is also borrowed as immutable

Looks like you want https://doc.rust-lang.org/std/vec/struct.Vec.html#method.retain

Though remember to invert the condition, because the condition should be true for items you want to keep
