Struct icu::datetime::fieldset::Combo

pub struct Combo<DT, Z> { /* private fields */ }

Struct for combining date/time fields with zone fields.

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

Examples

Two ways to construct the same combo field set (in this case, weekday with location-based zone):

use icu::datetime::fieldset::{Combo, E, L};

let field_set_1 = E::long().zone_l();
let field_set_2 = Combo::<E, L>::long();

assert_eq!(field_set_1, field_set_2);

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().zone_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().zone_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()).zone_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"
);
