# AugmentationSequence

An async sequence of augmented elements.

## Declaration

```swift
struct AugmentationSequence<Base, RandomTransformer, RandomNumberGenerator, Annotation> where Base : Sequence, RandomTransformer : RandomTransformer, RandomNumberGenerator : RandomNumberGenerator, Base.Element == AnnotatedFeature<RandomTransformer.Input, Annotation>, RandomTransformer.Input == RandomTransformer.Output
```
