Enum nix::sys::timerfd::ClockId

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

Available on crate feature time only.

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.
