Description
As described in the README, retain_mut has been deprecated with the release of Rust 1.61, which stabilized Vec::retain_mut and VecDeque::retain_mut.
I see this crate still makes peaks of 30k downloads a day, with Rust 1.61 having been released almost 2 years ago. Should an advisory be made for it?
