Struct nix::time::ClockId

pub struct ClockId(/* private fields */);

Available on crate feature time only.

Clock identifier

Newtype pattern around libc::clockid_t.

Implementations

impl ClockId

pub const fn from_raw(clk_id: clockid_t) -> Self

Creates ClockId from raw clockid_t

pub fn pid_cpu_clock_id(pid: Pid) -> Result<Self>

Available on crate feature process only.

Returns ClockId of a pid CPU-time clock

pub fn res(self) -> Result<TimeSpec>

Returns resolution of the clock id

pub fn now(self) -> Result<TimeSpec>

Returns the current time on the clock id

pub fn set_time(self, timespec: TimeSpec) -> Result<()>

Sets time to timespec on the clock id

pub const fn as_raw(self) -> clockid_t

Gets the raw clockid_t wrapped by self

pub const CLOCK_BOOTTIME: ClockId = _

Starts at zero when the kernel boots and increments monotonically in SI seconds while the machine is running.

pub const CLOCK_BOOTTIME_ALARM: ClockId = _

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

pub const CLOCK_MONOTONIC: ClockId = _

Increments in SI seconds.

pub const CLOCK_MONOTONIC_COARSE: ClockId = _

Like CLOCK_MONOTONIC, but optimized for execution time at the expense of accuracy.

pub const CLOCK_MONOTONIC_RAW: ClockId = _

Similar to CLOCK_MONOTONIC, but provides access to a raw hardware-based time that is not subject to NTP adjustments.

pub const CLOCK_PROCESS_CPUTIME_ID: ClockId = _

Returns the execution time of the calling process.

pub const CLOCK_REALTIME: ClockId = _

Increments as a wall clock should.

pub const CLOCK_REALTIME_ALARM: ClockId = _

Like CLOCK_REALTIME, but not settable.

pub const CLOCK_REALTIME_COARSE: ClockId = _

Like CLOCK_REALTIME, but optimized for execution time at the expense of accuracy.

pub const CLOCK_TAI: ClockId = _

International Atomic Time.

A nonsettable system-wide clock derived from wall-clock time but ignoring leap seconds.

pub const CLOCK_THREAD_CPUTIME_ID: ClockId = _

Returns the execution time of the calling thread.

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 Display for ClockId

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

Formats the value using the given formatter.

impl From<ClockId> for clockid_t

fn from(clock_id: ClockId) -> Self

Converts to this type from the input type.

impl From<i32> for ClockId

fn from(clk_id: clockid_t) -> Self

Converts to this type from the input type.

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) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq 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 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.
