Struct LocaleFallbackSolver 

pub struct LocaleFallbackSolver<R: for<'a> PolyL10nRulebook<'a> = ARulebook> {
    pub rulebook: R,
}

Entry point of poly_l10n.

A solver requires a Rulebook or ARulebook to process and solve locales. The latter is used by Self::default.

Examples

let solver = poly_l10n::LocaleFallbackSolver::<poly_l10n::ARulebook>::default();
assert_eq!(solver.solve_locale(poly_l10n::langid!("arb")), poly_l10n::langid!["arb", "ar-AE", "ara-AE", "arb-AE", "ar", "ara"]);

Fields

rulebook: R

Implementations

impl<R: for<'a> PolyL10nRulebook<'a>> LocaleFallbackSolver<R>

pub fn solve_locale<L: AsRef<LanguageIdentifier>>( &self, locale: L, ) -> Vec<LanguageIdentifier>

Find alternative fallbacks for the given locale as specified by the rulebook. This operation is recursive and expensive.

let solver = poly_l10n::LocaleFallbackSolver::<poly_l10n::Rulebook>::default();
assert_eq!(solver.solve_locale(poly_l10n::langid!("arb")), poly_l10n::langid!["arb", "ar-AE", "ara-AE", "arb-AE", "ar", "ara"]);

Trait Implementations

impl<R: Clone + for<'a> PolyL10nRulebook<'a>> Clone for LocaleFallbackSolver<R>

fn clone(&self) -> LocaleFallbackSolver<R>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<R: Debug + for<'a> PolyL10nRulebook<'a>> Debug for LocaleFallbackSolver<R>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<R: Default + for<'a> PolyL10nRulebook<'a>> Default for LocaleFallbackSolver<R>

fn default() -> LocaleFallbackSolver<R>

Returns the “default value” for a type.

impl<R: Copy + for<'a> PolyL10nRulebook<'a>> Copy for LocaleFallbackSolver<R>
