Struct Instant 

pub struct Instant { /* private fields */ }

A UTC label with nanosecond precision, preserving an inserted second.

Ordering is by UTC label, not by POSIX timestamp. Construction preserves a label; only a LeapTable can establish whether it occurred in UTC.

Implementations

impl Instant

pub const fn new(seconds: i64, nanos: u32) -> Option<Self>

An ordinary POSIX-labelled second and its fractional nanoseconds.

pub const fn leap_after(seconds: i64, nanos: u32) -> Option<Self>

The inserted second after seconds, which must label UTC 23:59:59. This does not assert that an insertion actually occurred on that date.

pub const fn seconds(self) -> i64

The POSIX label, or the preceding second’s label for a leap second. Not an elapsed-seconds coordinate; use LeapTable::shift for arithmetic.

pub const fn is_leap_second(self) -> bool

Whether this labels the inserted second after Self::seconds.

pub const fn nanos(self) -> u32

Nanoseconds within the labelled second, always less than one billion.
