Methods from Deref<Target = NaiveDate>

pub fn and_time(&self, time: NaiveTime) -> NaiveDateTime

Makes a new NaiveDateTime from the current date and given NaiveTime.

Example

use chrono::{NaiveDate, NaiveTime, NaiveDateTime};

let d = NaiveDate::from_ymd(2015, 6, 3);
let t = NaiveTime::from_hms_milli(12, 34, 56, 789);

let dt: NaiveDateTime = d.and_time(t);
assert_eq!(dt.date(), d);
assert_eq!(dt.time(), t);

pub fn and_hms(&self, hour: u32, min: u32, sec: u32) -> NaiveDateTime

Makes a new NaiveDateTime from the current date, hour, minute and second.

No leap second is allowed here; use NaiveDate::and_hms_* methods with a subsecond parameter instead.

Panics on invalid hour, minute and/or second.

Example

use chrono::{NaiveDate, NaiveDateTime, Datelike, Timelike, Weekday};

let d = NaiveDate::from_ymd(2015, 6, 3);

let dt: NaiveDateTime = d.and_hms(12, 34, 56);

pub fn succ(&self) -> NaiveDate

Makes a new NaiveDate for the next calendar date.

Panics when self is the last representable date.

Example

use chrono::NaiveDate;

assert_eq!(NaiveDate::from_ymd(2015,  6, 30).succ(), NaiveDate::from_ymd(2015, 7, 1));
assert_eq!(NaiveDate::from_ymd(2015, 12, 31).succ(), NaiveDate::from_ymd(2016, 1, 1));

pub fn succ_opt(&self) -> Option<NaiveDate>

Makes a new NaiveDate for the next calendar date.

Returns None when self is the last representable date.

Example

use chrono::NaiveDate;
use chrono::naive::MAX_DATE;

assert_eq!(NaiveDate::from_ymd(2015, 6, 3).succ_opt(),
           Some(NaiveDate::from_ymd(2015, 6, 4)));
assert_eq!(MAX_DATE.succ_opt(), None);

pub fn pred(&self) -> NaiveDate

Makes a new NaiveDate for the previous calendar date.

Panics when self is the first representable date.

Example

use chrono::NaiveDate;

assert_eq!(NaiveDate::from_ymd(2015, 6, 3).pred(), NaiveDate::from_ymd(2015,  6,  2));
assert_eq!(NaiveDate::from_ymd(2015, 6, 1).pred(), NaiveDate::from_ymd(2015,  5, 31));
assert_eq!(NaiveDate::from_ymd(2015, 1, 1).pred(), NaiveDate::from_ymd(2014, 12, 31));

pub fn pred_opt(&self) -> Option<NaiveDate>

Makes a new NaiveDate for the previous calendar date.

Returns None when self is the first representable date.

Example

use chrono::NaiveDate;
use chrono::naive::MIN_DATE;

assert_eq!(NaiveDate::from_ymd(2015, 6, 3).pred_opt(),
           Some(NaiveDate::from_ymd(2015, 6, 2)));

pub fn format_with_items<'a, I, B>(&self, items: I) -> DelayedFormat<I> where
    B: Borrow<Item<'a>>,
    I: Iterator<Item = B> + Clone, 

Formats the date with the specified formatting items. Otherwise it is the same as the ordinary format method.

The Iterator of items should be Cloneable, since the resulting DelayedFormat value may be formatted multiple times.

Example

use chrono::NaiveDate;
use chrono::format::strftime::StrftimeItems;

let fmt = StrftimeItems::new("%Y-%m-%d");
let d = NaiveDate::from_ymd(2015, 9, 5);
assert_eq!(d.format_with_items(fmt.clone()).to_string(), "2015-09-05");
assert_eq!(d.format("%Y-%m-%d").to_string(),             "2015-09-05");

The resulting DelayedFormat can be formatted directly via the Display trait.

assert_eq!(format!("{}", d.format_with_items(fmt)), "2015-09-05");

pub fn format(&self, fmt: &'a str) -> DelayedFormat<StrftimeItems<'a>>

Formats the date with the specified format string. See the format::strftime module on the supported escape sequences.

This returns a DelayedFormat, which gets converted to a string only when actual formatting happens. You may use the to_string method to get a String, or just feed it into print! and other formatting macros. (In this way it avoids the redundant memory allocation.)

A wrong format string does not issue an error immediately. Rather, converting or formatting the DelayedFormat fails. You are recommended to immediately use DelayedFormat for this reason.

Example

use chrono::NaiveDate;

let d = NaiveDate::from_ymd(2015, 9, 5);
assert_eq!(d.format("%Y-%m-%d").to_string(), "2015-09-05");
assert_eq!(d.format("%A, %-d %B, %C%y").to_string(), "Saturday, 5 September, 2015");

The resulting DelayedFormat can be formatted directly via the Display trait.

assert_eq!(format!("{}", d.format("%Y-%m-%d")), "2015-09-05");
assert_eq!(format!("{}", d.format("%A, %-d %B, %C%y")), "Saturday, 5 September, 2015");

pub fn iter_days(&self) -> NaiveDateDaysIterator

Returns an iterator that steps by days until the last representable date.

Example

let expected = [
    NaiveDate::from_ymd(2016, 2, 27),
    NaiveDate::from_ymd(2016, 2, 28),
    NaiveDate::from_ymd(2016, 2, 29),
    NaiveDate::from_ymd(2016, 3, 1),
];

let mut count = 0;
for (idx, d) in NaiveDate::from_ymd(2016, 2, 27).iter_days().take(4).enumerate() {
   assert_eq!(d, expected[idx]);
   count += 1;
}
assert_eq!(count, 4);

pub fn iter_weeks(&self) -> NaiveDateWeeksIterator

Returns an iterator that steps by weeks until the last representable date.

Example

let expected = [
    NaiveDate::from_ymd(2016, 2, 27),
    NaiveDate::from_ymd(2016, 3, 5),
    NaiveDate::from_ymd(2016, 3, 12),
    NaiveDate::from_ymd(2016, 3, 19),
];

let mut count = 0;
for (idx, d) in NaiveDate::from_ymd(2016, 2, 27).iter_weeks().take(4).enumerate() {
   assert_eq!(d, expected[idx]);
   count += 1;
}
assert_eq!(count, 4);
