Struct tantivy::DateTime

source · [−]

pub struct DateTime { /* private fields */ }

Expand description

A date/time value with second 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 fn from_unix_timestamp(unix_timestamp: i64) -> Self

Create new from UNIX timestamp

source

pub const fn from_utc(dt: OffsetDateTime) -> Self

Create new from OffsetDateTime

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

source

pub const fn from_primitive(dt: PrimitiveDateTime) -> Self

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_unix_timestamp(self) -> i64

Convert to UNIX timestamp

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.
