Struct JobsEventCounter

pub(super) struct JobsEventCounter(usize);

A value read from the Jobs Event Counter. See the README.md for more coverage of how the jobs event counter works.

Tuple Fields

0: usize

Implementations

impl JobsEventCounter

pub(super) const DUMMY: JobsEventCounter

pub(super) fn as_usize(self) -> usize

pub(super) fn is_sleepy(self) -> bool

The JEC “is sleepy” if the last thread to increment it was in the process of becoming sleepy. This is indicated by its value being even. When new jobs are posted, they check if the JEC is sleepy, and if so they incremented it.

pub(super) fn is_active(self) -> bool

The JEC “is active” if the last thread to increment it was posting new work. This is indicated by its value being odd. When threads get sleepy, they will check if the JEC is active, and increment it.

Trait Implementations

impl Clone for JobsEventCounter

fn clone(&self) -> JobsEventCounter

Returns a duplicate of the value.

const fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for JobsEventCounter

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for JobsEventCounter

fn eq(&self, other: &JobsEventCounter) -> bool

Tests for self and other values to be equal, and is used by ==.

const fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for JobsEventCounter

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

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

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

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

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

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

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
