…shtriplett Add VecDeque::resize_with This already exists on `Vec`; I'm just adding it to `VecDeque`. I wanted to resize a `VecDeque<Vec<T>>` when I didn't know `T: Clone`, so I couldn't use `.resize(n, Vec::new())`. With this I could do `.resize_with(n, Vec::new)` instead, which doesn't need `T: Clone`. Tracking issue: rust-lang#41758

There was a problem hiding this comment.
Suggested change
| pub fn resize_with(&mut self, new_len: usize, generator: impl FnMut()->T) { | |
| pub fn resize_with(&mut self, new_len: usize, generator: impl FnMut() -> T) { |
Also, we generally don't use arg: impl Trait in the standard library so I think this should be a type param instead.
