Struct TranslationStore 

pub struct TranslationStore { /* private fields */ }

In-memory store of translation entries loaded from YAML files on disk.

Cheaply cloneable — wraps an Arc internally. Created by TranslationStore::load. Used by the Translator extractor and the template engine’s t() function (registered by make_t_function).

Implementations

impl TranslationStore

pub fn load(path: &Path, default_locale: &str) -> Result<Self>

Loads translations from the given directory.

Each subdirectory of path is treated as a locale. YAML/YML files inside become namespaces whose keys are flattened with . separators.

Errors

Returns Error if the directory is unreadable or a YAML file cannot be parsed.

pub fn translate( &self, locale: &str, key: &str, kwargs: &[(&str, &str)], ) -> Result<String>

Translates key for the given locale, interpolating any {placeholder} values found in kwargs.

Falls back to the default locale and finally to the key itself if no entry is found.

pub fn translate_plural( &self, locale: &str, key: &str, count: i64, kwargs: &[(&str, &str)], ) -> Result<String>

Translates key with plural-rule selection based on count.

count is also injected into kwargs under the name count.

Cross-locale fallback

When an entry is missing in the requested locale, the default locale’s entry is used. Plural rule selection still uses the requesting locale’s rules (e.g., Ukrainian FEW / MANY categories applied against English one / other forms map to other). This keeps grammatical selection consistent with the user’s language even though the fallback copy is authored for a different one.

pub fn available_locales(&self) -> Vec<String>

Returns the list of locales discovered on disk (unordered).

pub fn default_locale(&self) -> &str

Returns the configured default locale.
