## Recap

    As these keys may not necessarily be part of the OpenAPI specification, some OpenAPI tools, for example [the OpenAPI validator](https://validator.swagger.io/), may not work with your generated schema.

## Recap

You can use Pydantic's `Field` to declare extra validations and metadata for model attributes.

		return summaryRangeToSumAddrRange(level, sumIdxBase, sumIdxLimit)

	// Find the first inUse index which is strictly greater than base.
	//
	// Because this function will never be asked remap the same memory
	// twice, this index is effectively the index at which we would insert
	// this new growth, and base will never overlap/be contained within
	// any existing range.

```
X-Token: foo
X-Token: bar
```

The response would be like:

```JSON
{
    "X-Token values": [
        "bar",
        "foo"
    ]
}
```

## Recap

Declare headers with `Header`, using the same common pattern as `Query`, `Path` and `Cookie`.
