Struct Date 

pub struct Date(pub NaiveDate);

A calendar date without a time zone, as HEY writes starts_on and ends_on.

Two dates compare and sort chronologically, so use <, > and == rather than looking for before and after.

Implementations

impl Date

pub fn new(year: i32, month: u32, day: u32) -> Option<Date>

The date at year, month and day, or None when the calendar has no such day.

pub fn parse(source: &str) -> Result<Date, Error>

Reads YYYY-MM-DD. An empty string is not a date and is rejected as one.

pub fn today() -> Date

Today where this machine is.

pub fn today_utc() -> Date

Today in UTC.

pub fn from_datetime(moment: &DateTime) -> Date

The date an instant falls on in UTC.

pub fn from_datetime_in<Tz: TimeZone>(moment: &DateTime, zone: &Tz) -> Date

The date an instant falls on in the given time zone, which is a different day from Date::from_datetime either side of midnight.

pub fn year(&self) -> i32

The calendar year.

pub fn month(&self) -> u32

The month, 1 through 12.

pub fn day(&self) -> u32

The day of the month, from 1.

pub fn weekday(&self) -> Weekday

The day of the week.

pub fn at_midnight_utc(&self) -> DateTime

Midnight UTC on this date.

UTC is the only zone this crate turns a date into an instant in: naming another would mean a time zone database, and the crate carries none. To land on midnight somewhere else, build the instant with a chrono::TimeZone of your own — zone.from_local_datetime(&date.0.and_time(NaiveTime::MIN)).

pub fn add_days(&self, days: i64) -> Option<Date>

The date days later, or earlier for a negative count; None past the calendar’s range.

pub fn add_months(&self, months: i32) -> Option<Date>

Adds months the way Go’s time.AddDate does: the day of the month is kept and a month too short to hold it rolls over into the next one, so 31 January plus one month is 3 March in a common year rather than 28 February.

pub fn add_years(&self, years: i32) -> Option<Date>

Adds years with the same rollover as Date::add_months: 29 February plus one year is 1 March.

pub fn days_since(&self, earlier: Date) -> i64

The whole days from earlier to this date, negative when this date came first.
