* iterators that don't support {@code remove()}. Otherwise, all optional operations are supported.
 * Null row keys, columns keys, and values are not supported.
 *
 * <p>Lookups by row key are often faster than lookups by column key, because the data is stored in
 * a {@code Map<R, Map<C, V>>}. A method call like {@code column(columnKey).get(rowKey)} still runs

## Other middlewares { #other-middlewares }

There are many other ASGI middlewares.

For example:

* [Uvicorn's `ProxyHeadersMiddleware`](https://github.com/encode/uvicorn/blob/master/uvicorn/middleware/proxy_headers.py)

  public static class GoodEqualsFactory {
    public static Object good(
        String a,
        int b,
        // oneConstantOnly doesn't matter since it's not nullable and can be only 1 value.
        @SuppressWarnings("unused") OneConstantEnum oneConstantOnly,
        // noConstant doesn't matter since it can only be null
        @SuppressWarnings("unused") @Nullable NoConstantEnum noConstant) {
      return new GoodEquals(a, b);
    }

 * <p>This service allows implementations to:</p>
 * <ul>
 *   <li>Pool identical objects to reduce memory footprint</li>
 *   <li>Intern objects for faster equality comparisons</li>
 *   <li>Apply custom optimization strategies</li>
 *   <li>Transform or modify objects during building</li>
 * </ul>

```json

  "message": "Hello World"
}
```

Of course, you will probably find much better ways to take advantage of this than formatting JSON. 😉

### `orjson` or Response Model { #orjson-or-response-model }

If what you are looking for is performance, you are probably better off using a [Response Model](../tutorial/response-model.md) than an `orjson` response.

  if [[ -z "${im_cmd}" ]] ; then
    echo "ImageMagick (convert or magick) does not exist."
    exit 1

  target_file=$(echo "$url" | sed -e "s#^file:/*#/#g")
  # Build format hint from MIME type for better ImageMagick compatibility
  format_hint=""
  case "${mimetype}" in
    "image/gif")  format_hint="gif:" ;;
    "image/tiff") format_hint="tiff:" ;;
    "image/png")  format_hint="png:" ;;

Sie möchten den externen Anbieter wahrscheinlich einmal testen, ihn aber nicht unbedingt bei jedem weiteren ausgeführten Test aufrufen.
