Trait FluentLabel 

pub trait FluentLabel {
    // Required methods
    fn fluent_label_domain() -> StaticFluentDomain;
    fn fluent_label_id() -> StaticFluentEntryId;

    // Provided methods
    fn try_localize_label<L: FluentLocalizer + ?Sized>(
        localizer: &L,
    ) -> Option<String> { ... }
    fn localize_label<L: FluentLocalizer + ?Sized>(localizer: &L) -> String { ... }
    fn fallback_label() -> String { ... }
}

A trait for types that have a Fluent label key representing the type itself.

This trait is automatically implemented by #[derive(EsFluentLabel)] for source types, and by #[derive(EsFluentVariants)] for each generated variant enum.

Required Methods

fn fluent_label_domain() -> StaticFluentDomain

Returns the validated static domain for this type-level label.

fn fluent_label_id() -> StaticFluentEntryId

Returns the validated static message id for this type-level label.

Provided Methods

fn try_localize_label<L: FluentLocalizer + ?Sized>( localizer: &L, ) -> Option<String>

Attempts to return the localized label for this type using an explicit localization context.

fn localize_label<L: FluentLocalizer + ?Sized>(localizer: &L) -> String

Returns the localized label for this type using an explicit localization context.

fn fallback_label() -> String

Returns deterministic fallback text for this type label without a runtime localization context.

Prefer Self::localize_label when UI code has a runtime manager. This helper is intended for generated metadata, tests, and integration scaffolding that cannot access app state.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
