pub struct ProcessTime(/* private fields */);
Expand description
CPU Time Used by The Whole Process
This is an opaque type similar to std::time::Instant
.
Use elapsed()
or duration_since()
to get meaningful time deltas.
Implementations§
§impl ProcessTime
impl ProcessTime
pub fn try_now() -> Result<ProcessTime, Error>
pub fn try_now() -> Result<ProcessTime, Error>
Get current CPU time used by a process process
pub fn now() -> ProcessTime
pub fn now() -> ProcessTime
Get current CPU time used by a process
§Panics
If CLOCK_THREAD_CPUTIME_ID
is not supported by the kernel.
On Linux, it was added in version 2.6.12 (year 2005).
On OpenBSD & FreeBSD support was added in 2013.
On MacOS, clock_gettime
was not supported until Sierra (2016).
pub fn try_elapsed(&self) -> Result<Duration, Error>
pub fn try_elapsed(&self) -> Result<Duration, Error>
Returns the amount of CPU time used from the previous timestamp to now.
pub fn elapsed(&self) -> Duration
pub fn elapsed(&self) -> Duration
Returns the amount of CPU time used from the previous timestamp to now.
§Panics
If ProcessTime::now()
panics.
pub fn duration_since(&self, timestamp: ProcessTime) -> Duration
pub fn duration_since(&self, timestamp: ProcessTime) -> Duration
Returns the amount of CPU time used from the previous timestamp.
pub fn as_duration(&self) -> Duration
pub fn as_duration(&self) -> Duration
Returns the total amount of CPU time used from the program start.
