* **Uvicorn**:
    * Will have the best performance, as it doesn't have much extra code apart from the server itself.

### Use the submodel as a type { #use-the-submodel-as-a-type }

And then we can use it as the type of an attribute:

{* ../../docs_src/body_nested_models/tutorial004_py310.py hl[18] *}

This would mean that **FastAPI** would expect a body similar to:

```JSON
{
    "name": "Foo",
    "description": "The pretender",
    "price": 42.0,
    "tax": 3.2,
    "tags": ["rock", "metal", "bar"],
    "image": {

import java.util.Iterator;
import java.util.List;
import org.jspecify.annotations.Nullable;

/**
 * An accumulator that selects the "top" {@code k} elements added to it, relative to a provided
 * comparator. "Top" can mean the greatest or the lowest elements, specified in the factory used to
 * create the {@code TopKSelector} instance.
 *
 * <p>If your input data is available as an {@link Iterable} or {@link Iterator}, prefer {@link

  private lateinit var server: MockWebServer
  private lateinit var client: OkHttpClient

  @BeforeEach
  fun setUp() {
    // Sockets on some platforms can have large buffers that mean writes do not block when
    // required. These socket factories explicitly set the buffer sizes on sockets created.
    server = MockWebServer()
    server.serverSocketFactory =

        .createTestSuite();
  }

  // Not specifying KNOWN_ORDER for PriorityQueue and PriorityBlockingQueue
  // even though they do have it, because our tests interpret KNOWN_ORDER to
  // also mean that the iterator returns the head element first, which those
  // don't.

  public Test testsForPriorityBlockingQueue() {
    return QueueTestSuiteBuilder.using(
            new TestStringQueueGenerator() {

     * This is an invalid state and should throw an exception.
     */
    @Test
    void testCheck_withNonNullStringAndZeroPointer_throwsException() {
        // A zero pointer should mean the string is null
        PacUnicodeString pacString = new PacUnicodeString((short) 0, (short) 0, 0);
        String testString = "not-null";

        // Expect a PACDecodingException to be thrown

Let's see the previous example again:

{* ../../docs_src/response_status_code/tutorial001_py39.py hl[6] *}

`201` is the status code for "Created".

But you don't have to memorize what each of these codes mean.

You can use the convenience variables from `fastapi.status`.

{* ../../docs_src/response_status_code/tutorial002_py39.py hl[1,6] *}

        .createTestSuite();
  }

  // Not specifying KNOWN_ORDER for PriorityQueue and PriorityBlockingQueue
  // even though they do have it, because our tests interpret KNOWN_ORDER to
  // also mean that the iterator returns the head element first, which those
  // don't.

  public Test testsForPriorityBlockingQueue() {
    return QueueTestSuiteBuilder.using(
            new TestStringQueueGenerator() {
