Source

pub struct MultiThreadDataLoader<O> { /* private fields */ }

Available on crate features std and dataset only.

Expand description

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

Implementations§

Source §

impl<O> MultiThreadDataLoader<O>

Source

pub fn new(dataloaders: Vec<Box<dyn DynDataLoader<O>>>) -> Self

Creates a new multi-threaded data loader.

§Arguments

dataloaders - The data loaders.

§Returns

The multi-threaded data loader.

Trait Implementations§

Source §

impl<O> DataLoader<O> for MultiThreadDataLoader<O>
where O: Send + 'static + Debug,

Source §

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

Returns a boxed iterator to iterate over the data loader.

Source §

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.
