Trait IterableDynamicDataProvider 

pub trait IterableDynamicDataProvider<M: DynamicDataMarker>: DynamicDataProvider<M> {
    // Required method
    fn iter_ids_for_marker(
        &self,
        marker: DataMarkerInfo,
    ) -> Result<BTreeSet<DataIdentifierCow<'_>>, DataError>;
}

A DynamicDataProvider that can iterate over all supported DataIdentifierCows for a certain marker.

The provider is not allowed to return Ok for requests that were not returned by iter_ids, and must not fail with a DataErrorKind::IdentifierNotFound for requests that were returned.

✨ Enabled with the alloc Cargo feature.
