Struct DateTime 

pub struct DateTime {
    pub year: i32,
    pub month: i32,
    pub day: i32,
    pub hours: i32,
    pub minutes: i32,
    pub seconds: i32,
    pub nanos: i32,
}

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

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.

Implementations

impl DateTime

pub fn to_rfc2822(&self) -> Option<String>

Converts this DateTime to an RFC 2822 string.

Returns None if any field is invalid (e.g., month > 12, day > 31).

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 Message for DateTime

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

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.
