Struct linux_futex::op::Op

pub struct Op { /* private fields */ }

The operation wake_op applies to the second futex.

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

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

Implementations

impl Op

pub fn assign(arg: u32) -> Self

Assign the argument to the futex value: value = arg

pub fn add(arg: u32) -> Self

Add the argument to the futex value: value += arg

pub fn or(arg: u32) -> Self

Bitwise-or the futex value with the argument: value |= arg

pub fn and_not(arg: u32) -> Self

Bitwise-and the futex value with the bitwise complement of the argument: value &= !arg

pub fn xor(arg: u32) -> Self

Xor the futex value with the argument: value ^= arg

pub fn assign_bit(bit: u32) -> Self

Assign 1 << bit to the futex value: value = 1 << bit

pub fn add_bit(bit: u32) -> Self

Add 1 << bit to the futex value: value += 1 << bit

pub fn set_bit(bit: u32) -> Self

Set the bitth bit of the futex value: value |= 1 << bit

pub fn clear_bit(bit: u32) -> Self

Clear the bitth bit of the futex value: value &= !(1 << bit)

pub fn toggle_bit(bit: u32) -> Self

Toggle the bitth bit of the futex value: value ^= 1 << bit

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 Op

fn clone(&self) -> Op

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Op

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

Formats the value using the given formatter.

impl PartialEq for Op

fn eq(&self, other: &Op) -> 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.
