Trait icu_provider::marker::KeyedDataMarker
source · [−]pub trait KeyedDataMarker: DataMarker {
const KEY: DataKey;
}Expand description
A DataMarker with a DataKey attached.
Structs implementing this trait are normally generated with the data_struct! macro.
Implementing this trait enables this marker to be used with the main DataProvider trait.
Most markers should be associated with a specific key and should therefore implement this
trait.
BufferMarker and AnyMarker are examples of markers that do not implement this trait
because they are not specific to a single key.
