How to check if VecDeque contains an element?

Having a VecDeque deq and an item, how can I find out if deq contains item? I can do it with an iterator:

deq.iter().find(|e| e == item).is_none()

But this is a lot of code. I just want to say deq.contains(item), but VecDeque has no such method (edit: not true anymore, see my answer). Any alternatives?

Solution

  • In Rust 1.12 a contains method was stabilized for LinkedList and VecDeque. Therefore the correct answer now is the obvious one:

    deq.contains(item)
