The custom-csv-dataset example implements the Dataset trait to retrieve dataset elements from a .csv file on disk. For this example, we use the diabetes dataset (original source).
The dataset only contains 442 records, so we use InMemDataset::from_csv(path) method to read the csv dataset file into a vector (in-memory) of DiabetesPatient records (struct) with the help of serde.
