Struct ThreadTime

pub struct ThreadTime(/* private fields */);

CPU Time Used by The Current Thread

This is an opaque type similar to std::time::Instant. Use elapsed() or duration_since() to get meaningful time deltas.

This type is non-thread-shareable (!Sync, !Send) because otherwise it’s to easy to mess up times from different threads. However, you can freely send Duration’s returned by elapsed() and duration_since().

Implementations

impl ThreadTime

pub fn try_now() -> Result<Self>

Get current CPU time used by a process process

pub fn now() -> Self

Panics

If GetThreadTimes fails. This may happen, for instance, in case of insufficient permissions.

See this MSDN page for details. If you prefer to handle such errors, consider using try_now.

pub fn try_elapsed(&self) -> Result<Duration>

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

pub fn elapsed(&self) -> Duration

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

Panics

If ThreadTime::now() panics.

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

Returns the amount of CPU time used by the current thread from the previous timestamp.

pub fn as_duration(&self) -> Duration

Returns the total amount of CPU time used from the program start.

Trait Implementations

impl Clone for ThreadTime

fn clone(&self) -> ThreadTime

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ThreadTime

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

Formats the value using the given formatter.

impl Hash for ThreadTime

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, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ThreadTime

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
