Struct cap_primitives::time::SystemTime

pub struct SystemTime { /* fields omitted */ }

A measurement of the system clock, useful for talking to external entities like the file system or other processes.

This corresponds to std::time::SystemTime.

Note that this SystemTime has no now, elapsed methods. To obtain the current time or measure the duration to the current time, you must first obtain a SystemClock, and then call SystemClock::now or SystemClock::elapsed instead. The UNIX_EPOCH constant is at SystemClock::UNIX_EPOCH.

Implementations

impl SystemTime

pub const fn from_std(std: SystemTime) -> Self

Constructs a new instance of Self from the given std::time::SystemTime.

pub const fn into_std(self) -> SystemTime

Constructs a new instance of std::time::SystemTime from the given Self.

pub fn duration_since(&self, earlier: Self) -> Result<Duration, SystemTimeError>

Returns the amount of time elapsed from another instant to this one.

This corresponds to std::time::SystemTime::duration_since.

pub fn checked_add(&self, duration: Duration) -> Option<Self>

Returns Some(t) where t is the time self + duration if t can be represented as SystemTime (which means it's inside the bounds of the underlying data structure), None otherwise.

This corresponds to std::time::SystemTime::checked_add.

pub fn checked_sub(&self, duration: Duration) -> Option<Self>

Returns Some(t) where t is the time self - duration if t can be represented as SystemTime (which means it's inside the bounds of the underlying data structure), None otherwise.

This corresponds to std::time::SystemTime::checked_sub.

Trait Implementations

impl Add<Duration> for SystemTime

type Output = Self

The resulting type after applying the + operator.

fn add(self, dur: Duration) -> Self

Panics

This function may panic if the resulting point in time cannot be represented by the underlying data structure. See SystemTime::checked_add for a version without panic.

impl AddAssign<Duration> for SystemTime

fn add_assign(&mut self, other: Duration)

Performs the += operation.

impl Clone for SystemTime

fn clone(&self) -> SystemTime

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for SystemTime

impl Debug for SystemTime

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

Formats the value using the given formatter.

impl Eq for SystemTime

impl From<SystemTime> for SystemTimeSpec

fn from(time: SystemTime) -> Self

Performs the conversion.

impl Hash for SystemTime

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.

impl Ord for SystemTime

fn cmp(&self, other: &SystemTime) -> Ordering

This method returns an Ordering between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<SystemTime> for SystemTime

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

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

fn le(&self, other: &SystemTime) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &SystemTime) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &SystemTime) -> bool
