Implementations

impl DateTime32

pub const MIN: DateTime32 = _

The earliest possible DateTime32 value.

pub const MAX: DateTime32 = _

The latest possible DateTime32 value.

pub fn timestamp(&self) -> u32

Returns the number of seconds since the UNIX epoch.

pub fn to_chrono(self) -> DateTime<Utc>

Returns the equivalent chrono::DateTime.

pub fn now() -> DateTime32

Returns the current time.

Panics

If the number of seconds since the UNIX epoch is greater than u32::MAX.

pub fn checked_duration_since(&self, earlier: DateTime32) -> Option<Duration32>

Returns the duration elapsed between earlier and this time, or None if earlier is later than this time.

pub fn saturating_duration_since(&self, earlier: DateTime32) -> Duration32

Returns duration elapsed between earlier and this time, or zero if earlier is later than this time.

pub fn checked_elapsed(&self, now: DateTime<Utc>) -> Option<Duration32>

Returns the duration elapsed since this time, or if this time is in the future, returns None.

pub fn saturating_elapsed(&self, now: DateTime<Utc>) -> Duration32

Returns the duration elapsed since this time, or if this time is in the future, returns zero.

pub fn checked_add(&self, duration: Duration32) -> Option<DateTime32>

Returns the time that is duration after this time. If the calculation overflows, returns None.

pub fn saturating_add(&self, duration: Duration32) -> DateTime32

Returns the time that is duration after this time. If the calculation overflows, returns DateTime32::MAX.

pub fn checked_sub(&self, duration: Duration32) -> Option<DateTime32>

Returns the time that is duration before this time. If the calculation underflows, returns None.

pub fn saturating_sub(&self, duration: Duration32) -> DateTime32

Returns the time that is duration before this time. If the calculation underflows, returns DateTime32::MIN.

Trait Implementations

impl PartialEq for DateTime32

fn eq(&self, other: &DateTime32) -> 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.
