Rollup merge of rust-lang#140625 - paolobarbolini:vec-extract-if-alt-is-retain_mut, r=Mark-Simulacrum Suggest `retain_mut` over `retain` as `Vec::extract_if` alternative The docs for `Vec::extract_if` suggest using `Vec::retain` if the user doesn't need the removed item. Given that `extract_if` gives a mutable reference to the evaluated element, `retain_mut` is the most appropriate alternative, not `retain`.
