Struct ExtractIf
#[must_use = "iterators are lazy and do nothing unless consumed; use `extract_if().for_each(drop)` to remove and discard elements"]
pub struct ExtractIf<'a, T: 'a, F: 'a, A: Allocator = Global> { pub(in ::collections::linked_list) list: &'a mut LinkedList<T, A>, pub(in ::collections::linked_list) it: Option<NonNull<Node<T>>>, pub(in ::collections::linked_list) pred: F, pub(in ::collections::linked_list) idx: usize, pub(in ::collections::linked_list) old_len: usize }This struct is created by the extract_if method on LinkedList.
