#[must_use]
pub enum Pop<T> {
    Empty,
    Data(T),
    Retry,
}

Data(T)

Some data has been successfully popped.

Retry

Lost the race for popping data to another concurrent steal operation. Try again.

Trait Implementations

impl<T: PartialOrd> PartialOrd<Pop<T>> for Pop<T>

fn partial_cmp(&self, other: &Pop<T>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Pop<T>) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Pop<T>) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Pop<T>) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Pop<T>) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
