Trait Dataset 

pub trait Dataset: Send + Sync {
    // Required methods
    fn len(&self) -> usize;
    fn get(&self, index: usize) -> DataItem;

    // Provided method
    fn is_empty(&self) -> bool { ... }
}

Trait for indexable datasets.

Implementations must be Send + Sync because DataLoader worker threads call get() concurrently via Arc<dyn Dataset>.

Required Methods

fn len(&self) -> usize

Total number of items in the dataset.

fn get(&self, index: usize) -> DataItem

Retrieve the item at index.

Panics

May panic if index >= len().

Provided Methods

fn is_empty(&self) -> bool

Whether the dataset is empty.

Implementors

impl Dataset for RecordDataset
