Struct Instant

pub struct Instant { /* private fields */ }

An instant is an exact point on the timeline, irrespective of time zone or calendar format, with millisecond precision.

Internally, this is represented by a 64-bit integer of seconds, and a 16-bit integer of milliseconds. This means that it will overflow (and thus be unsuitable for) instants past GMT 15:30:08, Sunday 4th December, 292,277,026,596 (yes, that’s a year)

Implementations

impl Instant

pub fn at(seconds: i64) -> Self

Creates a new Instant set to the number of seconds since the Unix epoch, and zero milliseconds.

pub fn at_ms(seconds: i64, milliseconds: i16) -> Self

Creates a new Instant set to the number of seconds since the Unix epoch, along with the number of milliseconds so far this second.

pub fn now() -> Self

Creates a new Instant set to the computer’s current time.

pub fn at_epoch() -> Self

Creates a new Instant set to the Unix epoch.

pub fn seconds(&self) -> i64

Returns the number of seconds at this instant

pub fn milliseconds(&self) -> i16

Returns the number of milliseconds at this instant

Trait Implementations

impl Add<Duration> for Instant

type Output = Instant

The resulting type after applying the + operator.

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

Performs the + operation.

impl Clone for Instant

fn clone(&self) -> Instant

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Instant

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

Formats the value using the given formatter.

impl Ord for Instant

fn cmp(&self, other: &Instant) -> 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 Instant

fn eq(&self, other: &Instant) -> 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 Instant

fn partial_cmp(&self, other: &Instant) -> 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.

impl Sub<Duration> for Instant

type Output = Instant

The resulting type after applying the - operator.

fn sub(self, duration: Duration) -> Self

Performs the - operation.
