Struct Ends 

pub struct Ends { /* private fields */ }

The two sequences a list’s header keeps, one per end.

A pop does not appear here on purpose. The cursors move outward on a push and never come back, so a sequence is used once for the life of the list.

Implementations

impl Ends

pub fn new() -> Ends

An empty list, with both ends starting from the middle of the range.

pub fn push_front(&mut self) -> Option<[u8; 8]>

The key for an element pushed onto the front, and the cursor moved down.

None once the front has been pushed to fifty six bits of times, which is a list that cannot exist rather than a case with a recovery.

pub fn push_back(&mut self) -> Option<[u8; 8]>

The key for an element pushed onto the back, and the cursor moved up.
