Expand description
Metadata statically associated with a particular DataKey
.
Fields (Non-exhaustive)§
This struct is marked as non-exhaustive
Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional
Struct { .. }
syntax; cannot be matched against without a wildcard ..
; and struct update syntax will not work.fallback_priority: LocaleFallbackPriority
What to prioritize when fallbacking on this DataKey
.
extension_key: Option<Key>
A Unicode extension keyword to consider when loading data for this DataKey
.
fallback_supplement: Option<LocaleFallbackSupplement>
Optional choice for additional fallbacking data required for loading this marker.
For more information, see LocaleFallbackConfig::fallback_supplement
.
singleton: bool
Whether the key has a singleton value, as opposed to per-locale values. Singleton keys behave differently, e.g. they never perform fallback, and can be optimized in data providers.
