Trait Implementations§

Source§

impl<D: Ord + Columnation, T: Ord + Columnation, R: Columnation> ContainerQueue<TimelyStack<(D, T, R)>> for TimelyStackQueue<(D, T, R)>

Source§

fn next_or_alloc(&mut self) -> Result<&(D, T, R), TimelyStack<(D, T, R)>>

Returns either the next item in the container, or the container itself.
Source§

fn is_empty(&self) -> bool

Indicates whether next_or_alloc will return Ok, and whether peek will return Some.
Source§

fn cmp_heads(&self, other: &Self) -> Ordering

Compare the heads of two queues, where empty queues come last.
Source§

fn from(list: TimelyStack<(D, T, R)>) -> Self
