Concept definition

template<class D>
concept ultra::src::EvaluationDataset = 
  (is_multi_dataset_v<D> && DataSet<decltype(std::declval<D>().selected())>)
  || DataSet<D>

Detailed Description

Concept modelling a dataset that provides examples for evaluation.

Supported forms:

• multi_dataset<T>: examples are taken from the currently selected dataset via selected()
• plain datasets (DataSet<T>): examples are taken directly from the dataset

This concept ensures that evaluators can uniformly access examples regardless of whether a single dataset or a multi-dataset container is used.
