Struct AbsoluteTime 

pub struct AbsoluteTime { /* private fields */ }

An absolute time which are binded to the system’s clock and never be zero except when timer is reset.

Implementations

impl AbsoluteTime

pub const MAX_NS: i64 = 1_000_000_000i64

max nanoseconds

impl AbsoluteTime

pub fn now() -> Self

Creates an instance with the current local time.

pub fn new_time(time_sec: i64, time_nsec: i64) -> Option<Self>

pub unsafe fn new_time_unchecked(time_sec: i64, time_nsec: i64) -> Self

Creates new instance for absolute time accepting the user input.

Automatically corrects the time_nsec value if it is larger than 999_999_999ns.

Arguments

time_sec - i64 a seconds in absolute notation.

time_nsec - i64 nanoseconds of absolute seconds value. Should not be larger than 999_999_999 which is defined by const Self::MAX_NS. In case if it is larger, the nsec will be rounded and an extra secons will be added.

Returns

An instance is returned. May panic on overflow.

pub fn seconds_cmp(&self, other: &Self) -> Ordering

Compares only full seconds without nanoseconds fraction (subnano).

pub fn add_sec(self, seconds: i64) -> Self

pub fn reset_nsec(self) -> Self

Trait Implementations

impl Add<RelativeTime> for AbsoluteTime

type Output = AbsoluteTime

The resulting type after applying the + operator.

fn add(self, rhs: RelativeTime) -> Self::Output

Performs the + operation.

impl AddAssign<RelativeTime> for AbsoluteTime

fn add_assign(&mut self, rhs: RelativeTime)

Performs the += operation.

impl Clone for AbsoluteTime

fn clone(&self) -> AbsoluteTime

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AbsoluteTime

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

Formats the value using the given formatter.

impl Display for AbsoluteTime

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

Formats the value using the given formatter.

impl<TZ: TimeZone> From<DateTime<TZ>> for AbsoluteTime

Convers the chrono DateTime into the AbsoluteTime using the TZ TimeZone taking the ns fraction of a second (subsec_nano) using timestamp_subsec_nanos function.

fn from(value: DateTime<TZ>) -> Self

Converts to this type from the input type.

impl From<Duration> for AbsoluteTime

Converts the Duration to RelativeTime taking the subsec_nanos for the time_nsec.

fn from(value: Duration) -> Self

Converts to this type from the input type.

impl ModeTimeType for AbsoluteTime

fn new(time_spec: timespec) -> Self

where Self: Sized,

Creates new instance from the two components: seconds and subnanoseconds of the seconds.

fn get_sec(&self) -> i64

Returns the seconds without the nanoseconds fraction.

fn get_nsec(&self) -> i64

Returns the nanoseconds fraction from seconds, not a full time in nanoseconds.

fn is_value_valid(&self) -> bool

Verifies that the timer is not set to zero. For the RelativeTime it always returns true.

fn get_flags() -> TimerSetTimeFlags

Returns the TimerSetTimeFlags which are autoinitialized for both types. This flags should be passed to timer.

impl Ord for AbsoluteTime

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

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for AbsoluteTime

fn eq(&self, other: &AbsoluteTime) -> 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.

impl PartialOrd for AbsoluteTime

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

Performs the - operation.

impl Sub for AbsoluteTime

type Output = AbsoluteTime

The resulting type after applying the - operator.

fn sub(self, rhs: Self) -> Self::Output
