# KeyedEncodingContainerProtocol

A type that provides a view into an encoder’s storage and is used to hold the encoded properties of an encodable type in a keyed manner.

## Declaration

```swift
protocol KeyedEncodingContainerProtocol
```

## Overview

Overview Encoders should provide types conforming to KeyedEncodingContainerProtocol for their format.
