Struct DateTime 

pub struct DateTime { /* private fields */ }

A date/time value with nanoseconds precision.

This timestamp does not carry any explicit time zone information. Users are responsible for applying the provided conversion functions consistently. Internally the time zone is assumed to be UTC, which is also used implicitly for JSON serialization.

All constructors and conversions are provided as explicit functions and not by implementing any From/Into traits to prevent unintended usage.

Implementations

impl DateTime

pub const MIN: DateTime

Minimum possible DateTime value.

pub const MAX: DateTime

Maximum possible DateTime value.

pub const fn from_timestamp_secs(seconds: i64) -> DateTime

Create new from UNIX timestamp in seconds

pub const fn from_timestamp_millis(milliseconds: i64) -> DateTime

Create new from UNIX timestamp in milliseconds

pub const fn from_timestamp_micros(microseconds: i64) -> DateTime

Create new from UNIX timestamp in microseconds.

pub const fn from_timestamp_nanos(nanoseconds: i64) -> DateTime

Create new from UNIX timestamp in nanoseconds.

pub fn from_utc(dt: OffsetDateTime) -> DateTime

Create new from OffsetDateTime

The given date/time is converted to UTC and the actual time zone is discarded.

pub fn from_primitive(dt: PrimitiveDateTime) -> DateTime

Create new from PrimitiveDateTime

Implicitly assumes that the given date/time is in UTC! Otherwise the original value must only be reobtained with Self::into_primitive().

pub const fn into_timestamp_secs(self) -> i64

Convert to UNIX timestamp in seconds.

pub const fn into_timestamp_millis(self) -> i64

Convert to UNIX timestamp in milliseconds.

pub const fn into_timestamp_micros(self) -> i64

Convert to UNIX timestamp in microseconds.

pub const fn into_timestamp_nanos(self) -> i64

Convert to UNIX timestamp in nanoseconds.

pub fn into_utc(self) -> OffsetDateTime

Convert to UTC OffsetDateTime

pub fn into_offset(self, offset: UtcOffset) -> OffsetDateTime

Convert to OffsetDateTime with the given time zone

pub fn into_primitive(self) -> PrimitiveDateTime

Convert to PrimitiveDateTime without any time zone

The value should have been constructed with Self::from_primitive(). Otherwise the time zone is implicitly assumed to be UTC.

pub fn truncate(self, precision: DateTimePrecision) -> DateTime

Truncates the microseconds value to the corresponding precision.
