# ComposedTemporalTransformer

A temporal transformer that composes two temporal transformers by applying them one after the other.

## Declaration

```swift
struct ComposedTemporalTransformer<Inner, Outer> where Inner : TemporalTransformer, Outer : TemporalTransformer, Inner.Output == Outer.Input
```

## Overview

Overview The inner transformer’s output must match the outer transformer input. The result of this transformer is equivalent to invoking outer(inner(x)) on an input x,
