Struct nix::time::ClockId

pub struct ClockId(_);

Clock identifier

Newtype pattern around clockid_t (which is just alias). It pervents bugs caused by accidentally passing wrong value.

Implementations

impl ClockId

pub fn from_raw(clk_id: clockid_t) -> Self

Creates ClockId from raw clockid_t

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

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 fn as_raw(self) -> clockid_t

Gets the raw clockid_t wrapped by self
