Implementations§

source§

impl ClockId

source

pub const CLOCK_BOOTTIME: ClockId = _

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

source

pub const CLOCK_BOOTTIME_ALARM: ClockId = _

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

source

pub const CLOCK_MONOTONIC: ClockId = _

Increments in SI seconds.

source

pub const CLOCK_MONOTONIC_COARSE: ClockId = _

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

source

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.

source

pub const CLOCK_PROCESS_CPUTIME_ID: ClockId = _

Returns the execution time of the calling process.

source

pub const CLOCK_REALTIME: ClockId = _

Increments as a wall clock should.

source

pub const CLOCK_REALTIME_ALARM: ClockId = _

Like CLOCK_REALTIME, but not settable.

source

pub const CLOCK_REALTIME_COARSE: ClockId = _

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

source

pub const CLOCK_TAI: ClockId = _

International Atomic Time.

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

source

pub const CLOCK_THREAD_CPUTIME_ID: ClockId = _

Returns the execution time of the calling thread.

source

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

Creates ClockId from raw clockid_t

source

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

Returns ClockId of a pid CPU-time clock

source

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

Returns resolution of the clock id

source

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

Returns the current time on the clock id

source

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

Sets time to timespec on the clock id

source

pub const fn as_raw(self) -> clockid_t

Gets the raw clockid_t wrapped by self
