Trait icu_provider::DataMarker

pub trait DataMarker: DynamicDataMarker {
    const INFO: DataMarkerInfo;

    // Provided method
    fn bind<P>(provider: P) -> DataProviderWithMarker<Self, P>
       where P: DataProvider<Self>,
             Self: Sized { ... }
}

A DynamicDataMarker with a DataMarkerInfo 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 marker 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 marker.

Note: DataMarkers are quasi-const-generic compile-time objects, and as such are expected to be unit structs. As this is not something that can be enforced by the type system, we currently only have a 'static bound on them (which is needed by a lot of our code).

Required Associated Constants

const INFO: DataMarkerInfo

The single DataMarkerInfo associated with this marker.

Provided Methods

fn bind<P>(provider: P) -> DataProviderWithMarker<Self, P>

where P: DataProvider<Self>, Self: Sized,

Binds this DataMarker to a provider supporting it.
