Struct DateTime 

pub struct DateTime { /* private fields */ }

A date and time value with nanosecond precision. Always in SVTC timezone.

Internally stored as nanoseconds since Unix epoch (1970-01-01T00:00:00Z). Only supports dates from 1970-01-01 onward.

Implementations

impl DateTime

pub fn new( year: i32, month: u32, day: u32, hour: u32, min: u32, sec: u32, nano: u32, ) -> Option<Self>

Create from year, month, day, hour, minute, second, nanosecond. Returns None if the date is invalid or before Unix epoch.

pub fn from_ymd_hms( year: i32, month: u32, day: u32, hour: u32, min: u32, sec: u32, ) -> Result<Self, TypeError>

pub fn from_nanos(nanos: u64) -> Self

Create from a primary u64 nanoseconds value. Values beyond MAX_SAFE_NANOS are rejected to prevent downstream i32 overflow in date().

pub fn to_nanos(&self) -> u64

Get the raw nanoseconds since epoch.

pub fn from_timestamp(timestamp: i64) -> Result<Self, TypeError>

pub fn from_timestamp_millis(millis: u64) -> Result<Self, TypeError>

pub fn from_timestamp_nanos(nanos: u128) -> Result<Self, TypeError>

pub fn timestamp(&self) -> i64

pub fn timestamp_millis(&self) -> i64

pub fn timestamp_nanos(&self) -> Result<i64, TypeError>

pub fn try_date(&self) -> Result<Date, TypeError>

pub fn date(&self) -> Date

pub fn time(&self) -> Time

pub fn to_nanos_since_epoch_u128(&self) -> u128

Convert to nanoseconds since Unix epoch as u128.

pub fn year(&self) -> i32

pub fn month(&self) -> u32

pub fn day(&self) -> u32

pub fn hour(&self) -> u32

pub fn minute(&self) -> u32

pub fn second(&self) -> u32

pub fn nanosecond(&self) -> u32

pub fn add_duration(&self, dur: &Duration) -> Result<Self, TypeError>

Add a Duration to this DateTime, handling calendar arithmetic for months/days.

Trait Implementations

impl Clone for DateTime

fn clone(&self) -> DateTime

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DateTime

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for DateTime

fn default() -> Self

Returns the “default value” for a type.

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

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for DateTime

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl GetType for DateTime

fn get_type() -> Type

impl Hash for DateTime

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

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl IntoValue for DateTime

fn into_value(self) -> Value

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.

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

where Self: Sized,

Compares and returns the minimum of two values.

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

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for DateTime

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

impl PartialOrd for DateTime

fn partial_cmp(&self, other: &DateTime) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl ToValue for DateTime

fn to_value(&self) -> Value

impl TryFromValue for DateTime

fn try_from_value(value: &Value) -> Result<Self, FromValueError>

Attempt to extract a value of this type from a Value.

fn from_value(value: &Value) -> Option<Self>

Extract from Value, returning None for Undefined or type mismatch.
