Trait DataLoader

pub trait DataLoader<O>: Send {
    // Required methods
    fn iter<'a>(&'a self) -> Box<dyn DataLoaderIterator<O> + 'a>;
    fn num_items(&self) -> usize;
}

Available on crate features std and dataset only.

A data loader that can be used to iterate over a dataset.

Required Methods

fn iter<'a>(&'a self) -> Box<dyn DataLoaderIterator<O> + 'a>

Returns a boxed iterator to iterate over the data loader.

fn num_items(&self) -> usize

The number of items (not the number of batches nor the number of iterations), corresponding to the items_total of the progress returned by the iterator.
