Struct tantivy::DateTime

source ·
pub struct DateTime { /* private fields */ }
Expand description

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§

source§

impl DateTime

source

pub const MIN: DateTime = _

Minimum possible DateTime value.

source

pub const MAX: DateTime = _

Maximum possible DateTime value.

source

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

Create new from UNIX timestamp in seconds

source

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

Create new from UNIX timestamp in milliseconds

source

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

Create new from UNIX timestamp in microseconds.

source

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

Create new from UNIX timestamp in nanoseconds.

source

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.

source

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().

source

pub const fn into_timestamp_secs(self) -> i64

Convert to UNIX timestamp in seconds.

source

pub const fn into_timestamp_millis(self) -> i64

Convert to UNIX timestamp in milliseconds.

source

pub const fn into_timestamp_micros(self) -> i64

Convert to UNIX timestamp in microseconds.

source

pub const fn into_timestamp_nanos(self) -> i64

Convert to UNIX timestamp in nanoseconds.

source

pub fn into_utc(self) -> OffsetDateTime

Convert to UTC OffsetDateTime

source

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

Convert to OffsetDateTime with the given time zone

source

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.

source

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

Truncates the microseconds value to the corresponding precision.
