Struct DateTime

#[non_exhaustive]
pub struct DateTime {
    pub year: i32,
    pub month: i32,
    pub day: i32,
    pub hours: i32,
    pub minutes: i32,
    pub seconds: i32,
    pub nanos: i32,
    pub time_offset: Option<TimeOffset>,
}

Represents civil time (or occasionally physical time).

This type can represent a civil time in one of a few possible ways:

• When utc_offset is set and time_zone is unset: a civil time on a calendar day with a particular offset from UTC.
• When time_zone is set and utc_offset is unset: a civil time on a calendar day in a particular time zone.
• When neither time_zone nor utc_offset is set: a civil time on a calendar day in local time.

The date is relative to the Proleptic Gregorian Calendar.

If year is 0, the DateTime is considered not to have a specific year. month and day must have valid, non-zero values.

This type may also be used to represent a physical time if all the date and time fields are set and either case of the time_offset oneof is set. Consider using Timestamp message for physical time instead. If your use case also would like to store the user’s timezone, that can be done in another field.

This type is more flexible than some applications may want. Make sure to document and validate your application’s limitations.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

year: i32

Optional. Year of date. Must be from 1 to 9999, or 0 if specifying a datetime without a year.

month: i32

Required. Month of year. Must be from 1 to 12.

day: i32

Required. Day of month. Must be from 1 to 31 and valid for the year and month.

hours: i32

Required. Hours of day in 24 hour format. Should be from 0 to 23. An API may choose to allow the value “24:00:00” for scenarios like business closing time.

minutes: i32

Required. Minutes of hour of day. Must be from 0 to 59.

seconds: i32

Required. Seconds of minutes of the time. Must normally be from 0 to 59. An API may allow the value 60 if it allows leap-seconds.

nanos: i32

Required. Fractions of seconds in nanoseconds. Must be from 0 to 999,999,999.

time_offset: Option<TimeOffset>

Optional. Specifies either the UTC offset or the time zone of the DateTime. Choose carefully between them, considering that time zone data may change in the future (for example, a country modifies their DST start/end dates, and future DateTimes in the affected range had already been stored). If omitted, the DateTime is considered to be in local time.

Implementations

impl DateTime

pub fn set_year<T: Into<i32>>(self, v: T) -> Self

Sets the value of year.

pub fn set_month<T: Into<i32>>(self, v: T) -> Self

Sets the value of month.

pub fn set_day<T: Into<i32>>(self, v: T) -> Self

Sets the value of day.

pub fn set_hours<T: Into<i32>>(self, v: T) -> Self

Sets the value of hours.

pub fn set_minutes<T: Into<i32>>(self, v: T) -> Self

Sets the value of minutes.

pub fn set_seconds<T: Into<i32>>(self, v: T) -> Self

Sets the value of seconds.

pub fn set_nanos<T: Into<i32>>(self, v: T) -> Self

Sets the value of nanos.

pub fn set_time_offset<T: Into<Option<TimeOffset>>>(self, v: T) -> Self

Sets the value of time_offset.

Trait Implementations

impl Clone for DateTime

fn clone(&self) -> DateTime

Returns a copy 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() -> DateTime

Returns the “default value” for a type.

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

where DateTime: Default,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

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 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.
