Enum icu_decimal::options::GroupingStrategy

source ·
#[non_exhaustive]
pub enum GroupingStrategy { Auto, Never, Always, Min2, }
Expand description

Configuration for how often to render grouping separators.

§Examples

use icu::decimal::options;
use icu::decimal::FixedDecimalFormatter;
use icu::locid::Locale;
use writeable::assert_writeable_eq;

let locale = Locale::UND;
let mut options: options::FixedDecimalFormatterOptions = Default::default();
options.grouping_strategy = options::GroupingStrategy::Min2;
let fdf = FixedDecimalFormatter::try_new(&locale.into(), options)
    .expect("locale should be present");

let one_thousand = 1000.into();
assert_writeable_eq!(fdf.format(&one_thousand), "1000");

let ten_thousand = 10000.into();
assert_writeable_eq!(fdf.format(&ten_thousand), "10,000");

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

Auto

Render grouping separators according to locale preferences.

§

Never

Never render grouping separators.

§

Always

Always render grouping separators.

For FixedDecimalFormatter, GroupingStrategy::Always has the same behavior as GroupingStrategy::Auto.

§

Min2

Render grouping separators only if there are at least 2 digits before the final grouping separator. In most locales, this means that numbers between 1000 and 9999 do not get grouping separators, but numbers 10,000 and above will.
