i18n_inflector

i18n_inflector is a Rust crate that provides a comprehensive set of inflection rules for multiple languages, allowing you to easily convert words between different forms (e.g., singular to plural, plural to singular) in an internationalized context.

Example

use i18n_inflector::{language_rules, LanguageRules};

fn main() -> i18n_inflector::Result<()> {
    // English
    let en = language_rules("en")?;
    assert_eq!(en.singularize("users"), "user");
    assert_eq!(en.singularize("categories"), "category");

    let plurals = en.pluralize("user");
    assert!(plurals.iter().any(|v| v == "users"));

    // Spanish
    assert_eq!(language_rules("es")?.singularize("ciudades"), "ciudad");

    // French
    assert_eq!(language_rules("fr")?.singularize("journaux"), "journal");

    // Japanese
    assert_eq!(language_rules("ja")?.singularize("user"), "user");

    // Unsupported locale returns an error
    assert!(language_rules("xx").is_err());
    
    Ok(())
}
