Struct tantivy_columnar::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.

Trait Implementations

Formats the value using the given formatter.

impl Default for DateTime

fn default() -> DateTime

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for DateTime

fn deserialize<__D>( __deserializer: __D ) -> Result<DateTime, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

impl MonotonicallyMappableToU64 for DateTime

fn to_u64(self) -> u64

Converts a value to u64.

fn from_u64(val: u64) -> Self

Converts a value from u64

impl Ord for DateTime

fn cmp(&self, other: &DateTime) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for DateTime

fn eq(&self, other: &DateTime) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for DateTime

fn serialize<__S>( &self, __serializer: __S ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,
