Enum nix::sys::timerfd::ClockId

#[repr(i32)]
#[non_exhaustive]
pub enum ClockId {
    CLOCK_REALTIME,
    CLOCK_MONOTONIC,
    CLOCK_BOOTTIME,
    CLOCK_REALTIME_ALARM,
    CLOCK_BOOTTIME_ALARM,
}

The type of the clock used to mark the progress of the timer. For more details on each kind of clock, please refer to timerfd_create(2).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

CLOCK_REALTIME

A settable system-wide real-time clock.

CLOCK_MONOTONIC

A non-settable monotonically increasing clock.

Does not change after system startup. Does not measure time while the system is suspended.

CLOCK_BOOTTIME

Like CLOCK_MONOTONIC, except that CLOCK_BOOTTIME includes the time that the system was suspended.

CLOCK_REALTIME_ALARM

Like CLOCK_REALTIME, but will wake the system if it is suspended.

CLOCK_BOOTTIME_ALARM

Like CLOCK_BOOTTIME, but will wake the system if it is suspended.

Trait Implementations

impl Clone for ClockId

fn clone(&self) -> ClockId

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ClockId

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

Formats the value using the given formatter.

impl Hash for ClockId

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where
    H: Hasher,
    Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for ClockId

fn cmp(&self, other: &ClockId) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl PartialEq<ClockId> for ClockId

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

impl PartialOrd<ClockId> for ClockId

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

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

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

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

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

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

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

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

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

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