Struct cpu_time::ProcessTime

pub struct ProcessTime(_);

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.

Methods

impl ProcessTime

pub fn now() -> ProcessTime

Get current CPU time used by a process process

Panics

This method panics if linux kernel doesn't support CLOCK_PROCESS_CPUTIME_ID, which works since linux 2.6.12 (~ year 2005).

pub fn elapsed(&self) -> Duration

Returns the amount of CPU time used from the previous timestamp to now.

pub fn duration_since(&self, timestamp: ProcessTime) -> Duration

Returns the amount of CPU time used from the previous timestamp.

Trait Implementations

impl Copy for ProcessTime

impl Clone for ProcessTime

fn clone(&self) -> ProcessTime

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl PartialEq for ProcessTime

fn eq(&self, other: &ProcessTime) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &ProcessTime) -> bool

This method tests for !=.

impl Eq for ProcessTime

impl Debug for ProcessTime

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

Formats the value using the given formatter.

impl Hash for ProcessTime

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,

Feeds a slice of this type into the given [Hasher].
