Struct PluralRules

pub struct PluralRules { /* private fields */ }

The main structure for selecting plural rules.

Examples

use intl_pluralrules::{PluralRules, PluralRuleType, PluralCategory};
use unic_langid::LanguageIdentifier;

let langid: LanguageIdentifier = "naq".parse().expect("Parsing failed.");
let pr_naq = PluralRules::create(langid, PluralRuleType::CARDINAL).unwrap();
assert_eq!(pr_naq.select(1), Ok(PluralCategory::ONE));
assert_eq!(pr_naq.select("2"), Ok(PluralCategory::TWO));
assert_eq!(pr_naq.select(5.0), Ok(PluralCategory::OTHER));

Implementations

impl PluralRules

pub fn create<L: Into<LanguageIdentifier>>( langid: L, prt: PluralRuleType, ) -> Result<Self, &'static str>

Returns an instance of PluralRules.

Examples

use intl_pluralrules::{PluralRules, PluralRuleType, PluralCategory};
use unic_langid::LanguageIdentifier;

let langid: LanguageIdentifier = "naq".parse().expect("Parsing failed.");
let pr_naq = PluralRules::create(langid, PluralRuleType::CARDINAL);
assert_eq!(pr_naq.is_ok(), !pr_naq.is_err());

let langid: LanguageIdentifier = "xx".parse().expect("Parsing failed.");
let pr_broken = PluralRules::create(langid, PluralRuleType::CARDINAL);
assert_eq!(pr_broken.is_err(), !pr_broken.is_ok());

pub fn select<N: TryInto<PluralOperands>>( &self, number: N, ) -> Result<PluralCategory, &'static str>

Returns a result of the plural category for the given input.

If the input is not numeric.

Examples

use intl_pluralrules::{PluralRules, PluralRuleType, PluralCategory};
use unic_langid::LanguageIdentifier;

let langid: LanguageIdentifier = "naq".parse().expect("Parsing failed.");
let pr_naq = PluralRules::create(langid, PluralRuleType::CARDINAL).unwrap();
assert_eq!(pr_naq.select(1), Ok(PluralCategory::ONE));
assert_eq!(pr_naq.select(2), Ok(PluralCategory::TWO));
assert_eq!(pr_naq.select(5), Ok(PluralCategory::OTHER));

pub fn get_locales(prt: PluralRuleType) -> Vec<LanguageIdentifier>

Returns a list of the available locales.

Examples

use intl_pluralrules::{PluralRules, PluralRuleType};

assert_eq!(
    PluralRules::get_locales(PluralRuleType::CARDINAL).is_empty(),
    false
);

pub fn get_locale(&self) -> &LanguageIdentifier

Returns the locale name for this PluralRule instance.

Examples

use intl_pluralrules::{PluralRules, PluralRuleType};
use unic_langid::LanguageIdentifier;

let langid: LanguageIdentifier = "naq".parse().expect("Parsing failed.");
let pr_naq = PluralRules::create(langid.clone(), PluralRuleType::CARDINAL).unwrap();
assert_eq!(pr_naq.get_locale(), &langid);

Trait Implementations

impl Clone for PluralRules

fn clone(&self) -> PluralRules

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
