Struct icu_datetime::fieldset::Combo

source · 
pub struct Combo<DT, Z> { /* private fields */ }
Expand description

Struct for combining date/time fields with zone fields.

This struct produces “composite field sets” as defined in UTS 35.

This struct does not have its own constructor, but it can be produced via factory functions on the other field sets.

§Examples

Format the weekday, hour, and location-based zone:

use icu::datetime::fieldset::{Combo, ET, L};
use icu::datetime::DateTimeFormatter;
use icu::locale::locale;
use icu::timezone::IxdtfParser;
use writeable::assert_try_writeable_eq;

// Note: Combo type can be elided, but it is shown here for demonstration
let formatter = DateTimeFormatter::<Combo<ET, L>>::try_new(
    &locale!("en-US").into(),
    ET::short().hm().l(),
)
.unwrap();

let zdt = IxdtfParser::new().try_location_only_from_str(
    "2024-10-18T15:44[America/Los_Angeles]",
)
.unwrap();

assert_try_writeable_eq!(
    formatter.convert_and_format(&zdt),
    "Fri, 3:44 PM Los Angeles Time"
);

Same thing with a fixed calendar formatter:

use icu::calendar::Gregorian;
use icu::datetime::fieldset::{Combo, ET, L};
use icu::datetime::FixedCalendarDateTimeFormatter;
use icu::locale::locale;
use icu::timezone::IxdtfParser;
use writeable::assert_try_writeable_eq;

// Note: Combo type can be elided, but it is shown here for demonstration
let formatter = FixedCalendarDateTimeFormatter::<_, Combo<ET, L>>::try_new(
    &locale!("en-US").into(),
    ET::short().hm().l(),
)
.unwrap();

let zdt = IxdtfParser::new().try_location_only_iso_from_str(
    "2024-10-18T15:44[America/Los_Angeles]",
)
.unwrap()
.to_calendar(Gregorian);

assert_try_writeable_eq!(
    formatter.format(&zdt),
    "Fri, 3:44 PM Los Angeles Time"
);

Mix a dynamic DateFieldSet with a static time zone:

use icu::datetime::fieldset::{Combo, YMD, Vs, dynamic::DateFieldSet};
use icu::datetime::DateTimeFormatter;
use icu::locale::locale;
use icu::timezone::IxdtfParser;
use writeable::assert_try_writeable_eq;

// Note: Combo type can be elided, but it is shown here for demonstration
let formatter = DateTimeFormatter::<Combo<DateFieldSet, Vs>>::try_new(
    &locale!("en-US").into(),
    DateFieldSet::YMD(YMD::long()).v(),
)
.unwrap();

let zdt = IxdtfParser::new().try_location_only_from_str(
    "2024-10-18T15:44[America/Los_Angeles]",
)
.unwrap();

assert_try_writeable_eq!(
    formatter.convert_and_format(&zdt),
    "October 18, 2024 PT"
);
