E `Field` do Pydantic retorna uma instância de `FieldInfo` também.

`Body` também retorna objetos de uma subclasse de `FieldInfo` diretamente. E tem outras que você verá mais tarde que são subclasses da classe `Body`.

Lembre-se que quando você importa `Query`, `Path`, e outros de `fastapi`, esse são na realidade funções que retornam classes especiais.

### 2. Create a sample OPA Policy

In another terminal, create a policy that allows root user all access and for all other users denies `PutObject`:

```sh
cat > example.rego <<EOF
package httpapi.authz

import input

  ZERO(0),
  /** Test a one-element collection. */
  ONE(1),
  /** Test a three-element collection. */
  SEVERAL(3),
  /*
   * TODO: add VERY_LARGE, noting that we currently assume that the fourth
   * sample element is not in any collection
   */

  ANY(ZERO, ONE, SEVERAL);

  private final Set<Feature<? super Collection>> implied;
  private final @Nullable Integer numElements;

  CollectionSize(int numElements) {

  ZERO(0),
  /** Test a one-element collection. */
  ONE(1),
  /** Test a three-element collection. */
  SEVERAL(3),
  /*
   * TODO: add VERY_LARGE, noting that we currently assume that the fourth
   * sample element is not in any collection
   */

  ANY(ZERO, ONE, SEVERAL);

  private final Set<Feature<? super Collection>> implied;
  private final @Nullable Integer numElements;

  CollectionSize(int numElements) {

        <my.filter.value>hello</my.filter.value>
    </properties>

    <profiles>
        <profile>
            <id>two-conditions</id>
            <activation>
                <file>
                    <exists>simple.xml</exists>
                </file>
                <property>
                    <name>myproperty</name>
                    <value>test</value>
                </property>
            </activation>

# Code blocks { #code-blocks }

Some text

```python
# This is a sample Python code block
def hello_world():
    # Comment with indentation
    print("Hello, world!")  # Print greeting
```

Some more text

The following block is missing first line:

```toml
title = "TOML Example"  # Title of the document
```

And more text

```console
// Use the command "live" and pass the language code as a CLI argument

По указанным причинам текущие версии до сих пор `0.x.x`. Это говорит о том, что каждая версия может содержать обратно несовместимые изменения, следуя [Семантическому версионированию](https://semver.org/).

Уже сейчас вы можете создавать приложения в продакшн, используя **FastAPI** (и скорее всего так и делаете), главное убедиться в том, что вы используете версию, которая корректно работает с вашим кодом.
