Struct datetime::Instant

pub struct Instant { /* fields omitted */ }

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)

Methods

impl Instant

fn at(seconds: i64) -> Instant

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

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

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

fn now() -> Instant

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

fn at_epoch() -> Instant

Creates a new Instant set to the Unix epoch.

fn seconds(&self) -> i64

Returns the number of seconds at this instant

fn milliseconds(&self) -> i16

Returns the number of milliseconds at this instant
