impl ClockId

Increments in SI seconds.

pub const CLOCK_MONOTONIC_COARSE: ClockId

Available on linux_android or Emscripten or Fuchsia only.

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

Like CLOCK_REALTIME, but not settable.

pub const CLOCK_REALTIME_COARSE: ClockId

Available on linux_android or Emscripten or Fuchsia only.

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

pub const CLOCK_TAI: ClockId

Available on linux_android or Emscripten or Fuchsia only.

International Atomic Time.

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

pub const CLOCK_THREAD_CPUTIME_ID: ClockId

Available on linux_android or apple_targets or freebsdlike or Emscripten or Fuchsia only.

Returns the execution time of the calling thread.

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

Creates ClockId from raw clockid_t

Available on non-Redox only.

Returns resolution of the clock id

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

Returns the current time on the clock id

Available on neither iOS nor tvOS nor watchOS nor Redox nor HermitCore.

Sets time to timespec on the clock id

pub const fn as_raw(self) -> clockid_t

Gets the raw clockid_t wrapped by self
