A double-ended sequence that allows querying, insertion and deletion at both ends.
fn front<'a>(&'a self) -> std::option::Option
Provide a reference to the front element, or None if the sequence is empty
fn front_mut<'a>(&'a mut self) -> std::option::Option
Provide a mutable reference to the front element, or None if the sequence is empty
fn back<'a>(&'a self) -> std::option::Option
Provide a reference to the back element, or None if the sequence is empty
fn back_mut<'a>(&'a mut self) -> std::option::Option
Provide a mutable reference to the back element, or None if the sequence is empty
fn push_front(&mut self, elt: T)
Insert an element first in the sequence
fn push_back(&mut self, elt: T)
Insert an element last in the sequence
fn pop_back(&mut self) -> std::option::Option
Remove the last element and return it, or None if the sequence is empty
fn pop_front(&mut self) -> std::option::Option
Remove the first element and return it, or None if the sequence is empty
