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.
