impl<'a, I: Iterator<Item = B> + Clone, B: Borrow<Item<'a>>> DelayedFormat<I>

fn new(date: Option<NaiveDate>, time: Option<NaiveTime>, items: I) -> DelayedFormat<I>

Makes a new DelayedFormat value out of local date and time.

fn new_with_offset<Off>(date: Option<NaiveDate>, time: Option<NaiveTime>, offset: &Off, items: I) -> DelayedFormat<I>
where
    Off: Offset + Display,

Makes a new DelayedFormat value out of local date and time and UTC offset.

fn write_to(&self, w: &mut impl Write + ?Sized) -> Result

Formats DelayedFormat into a core::fmt::Write instance.

This function returns a core::fmt::Error if formatting into the core::fmt::Write instance fails.

Example

Writing to a String

let dt = chrono::DateTime::from_timestamp(1643723400, 123456789).unwrap();
let df = dt.format("%Y-%m-%d %H:%M:%S%.9f");
let mut buffer = String::new();
let _ = df.write_to(&mut buffer);
