Enum IsLeapSec 

pub enum IsLeapSec {
    None,
    Add,
    Sub,
}

Indicates whether a queried instant falls exactly on a leap second transition.

This is returned by LeapInfo::is_leap_sec and is only ever set to a non-None value when the queried timestamp is exactly at the moment a leap second is inserted or removed.

• IsLeapSec::Add is returned for the inserted leap second (e.g. 23:59:60).
• IsLeapSec::Sub is returned for a negative (subtracted) leap second.
• IsLeapSec::None is returned for all normal seconds.

Variants

None

This instant is not a leap second.

Add

This instant is a positive leap second (a second is being inserted).

Example: 2015-06-30 23:59:60 UTC.

Sub

This instant is a negative leap second (a second is being removed).

Perhaps this would work by having clocks skip the 59th second of a minute, e.g. 2015-06-30 23:59:58 UTC → 2015-07-01 00:00:00 UTC.

Trait Implementations

impl Clone for IsLeapSec

fn clone(&self) -> IsLeapSec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for IsLeapSec

impl Debug for IsLeapSec

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

Formats the value using the given formatter.

impl Default for IsLeapSec

fn default() -> IsLeapSec

Returns the “default value” for a type.

impl Eq for IsLeapSec

impl PartialEq for IsLeapSec

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