Struct linux_futex::op::Cmp

pub struct Cmp { /* private fields */ }

The comparison wake_op applies to the old value of the second futex.

A Cmp must be combined with an Op by using the plus operator. For example: Op::assign(1) + Cmp::eq(0)

The argument to any comparison must be below 1 << 12 (= 4096).

Implementations

impl Cmp

pub fn eq(value: u32) -> Self

Check if the old value of the futex equals this value.

pub fn ne(value: u32) -> Self

Check if the old value of the futex does not equal this value.

pub fn lt(value: u32) -> Self

Check if the old value of the futex is less than this value.

pub fn le(value: u32) -> Self

Check if the old value of the futex is less than or equal to this value.

pub fn gt(value: u32) -> Self

Check if the old value of the futex is greater than this value.

pub fn ge(value: u32) -> Self

Check if the old value of the futex is greater than or equal to this value.

Trait Implementations

impl Add<Cmp> for Op

type Output = OpAndCmp

The resulting type after applying the + operator.

fn add(self, cmp: Cmp) -> OpAndCmp

Performs the + operation.

impl Clone for Cmp

fn clone(&self) -> Cmp

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Cmp

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

Formats the value using the given formatter.

impl PartialEq for Cmp

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

This method tests for self and other values to be equal, and is used by ==.

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

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