Enum Language 

#[non_exhaustive]
pub enum Language {
    English,
    Portuguese,
}

Languages supported by the internationalization system.

Single source of truth for product locales in this binary. Do not use bool / raw String / integers for language in APIs.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

English

Neutral English (en) — default / agent-stable technical baseline.

Portuguese

Brazilian Portuguese (pt-BR) — mandatory MVP pair with en.

Implementations

impl Language

pub const AVAILABLE: &'static [Language]

Locales compiled into the default binary (MVP: en, pt-BR only).

pub const fn bcp47(self) -> &'static str

Canonical BCP47 tag for this product locale.

English is neutral en (not en-US alone). Portuguese is always pt-BR.

pub fn language_identifier(self) -> LanguageIdentifier

Structured BCP47 identifier (unic-langid).

Built-in tags are compile-time constants (en, pt-BR). On parse failure (should never happen), falls back to the default undetermined identifier — no panic on product paths (G-SEC-07).

pub const fn fallback(self) -> Language

Base fallback language for regionals (MVP: English).

pub const fn direction(self) -> TextDirection

Writing direction for this locale.

pub const fn script(self) -> &'static str

ISO 15924 script subtag (MVP Latin only).

pub fn from_langid(id: &LanguageIdentifier) -> Option<Language>

Maps a negotiated LanguageIdentifier to a product Language.

Matches primary language subtag: en* → English, pt* → Portuguese. Region-specific product choice for Portuguese is always pt-BR in MVP (no pt-PT variant compiled without a feature).
