pub struct ConcatDataset { /* private fields */ }

Concatenate two or more datasets end-to-end.

All datasets must share the same feature and target shapes.

Implementations

impl ConcatDataset

pub fn new(datasets: Vec<Box<dyn Dataset>>) -> Self

Create a concatenation of the given datasets.

Panics

Panics if datasets is empty.
