Implementations

impl PercentFormatter<DecimalFormatter>

pub fn try_new_with_buffer_provider( provider: &(impl BufferProvider + ?Sized), prefs: PercentFormatterPreferences, options: PercentFormatterOptions, ) -> Result<Self, DataError>

A version of [Self :: try_new] that uses custom data provided by a BufferProvider.

✨ Enabled with the serde feature.

📚 Help choosing a constructor

pub fn try_new( prefs: PercentFormatterPreferences, options: PercentFormatterOptions, ) -> Result<Self, DataError>

Creates a new PercentFormatter from compiled locale data and an options bag.

✨ Enabled with the compiled_data Cargo feature.

📚 Help choosing a constructor

pub fn try_new_unstable<D>( provider: &D, prefs: PercentFormatterPreferences, options: PercentFormatterOptions, ) -> Result<Self, DataError>

where D: ?Sized + DataProvider<PercentEssentialsV1> + DataProvider<DecimalSymbolsV1> + DataProvider<DecimalDigitsV1>,

A version of Self::try_new that uses custom data provided by a DataProvider.

⚠️ The bounds on provider may change over time, including in SemVer minor releases.

pub fn format<'l>(&'l self, value: &'l Decimal) -> FormattedPercent<'l>

Formats a [Decimal] value for the given percent code.

Examples

use icu::experimental::dimension::percent::formatter::PercentFormatter;
use icu::locale::locale;
use writeable::Writeable;

let locale = locale!("en-US").into();
let fmt = PercentFormatter::try_new(locale, Default::default()).unwrap();
let value = "12345.67".parse().unwrap();
let formatted_percent = fmt.format(&value);
let mut sink = String::new();
formatted_percent.write_to(&mut sink).unwrap();
assert_eq!(sink.as_str(), "12,345.67%");

impl<R> PercentFormatter<R>

where R: AsRef<DecimalFormatter>,

pub fn try_new_with_decimal_formatter( prefs: PercentFormatterPreferences, decimal_formatter: R, options: PercentFormatterOptions, ) -> Result<Self, DataError>

Creates a new PercentFormatter from compiled locale data, an options bag and fixed decimal formatter.

✨ Enabled with the compiled_data Cargo feature.
