Examples

Formatting and lists in Spanish

let list_formatter = ListFormatter::try_new_and(
    locale!("es").into(),
    ListFormatterOptions::default().with_length(ListLength::Wide),
)
.expect("locale should be present");

assert_writeable_eq!(
    list_formatter.format(["España", "Suiza"].iter()),
    "España y Suiza",
);

// The Spanish 'y' sometimes becomes an 'e':
assert_writeable_eq!(
    list_formatter.format(["España", "Suiza", "Italia"].iter()),
    "España, Suiza e Italia",
);

Formatting or lists in Thai

let list_formatter = ListFormatter::try_new_or(
    locale!("th").into(),
    ListFormatterOptions::default().with_length(ListLength::Short),
)
.expect("locale should be present");

// We can use any Writeables as inputs
assert_writeable_eq!(list_formatter.format(1..=3), "1, 2 หรือ 3",);

Formatting unit lists in English

let list_formatter = ListFormatter::try_new_unit(
    locale!("en").into(),
    ListFormatterOptions::default().with_length(ListLength::Wide),
)
.expect("locale should be present");

assert_writeable_eq!(
    list_formatter.format(["1ft", "2in"].iter()),
    "1ft, 2in",
);

Note: this last example is not fully internationalized. See icu4x/2192 for full unit handling.
