## Використання `Annotated` у типі параметра `q`

Пам’ятаєте, як я раніше розповідав, що `Annotated` можна використовувати для додавання метаданих до параметрів у [Вступі до типів Python](../python-types.md#type-hints-with-metadata-annotations){.internal-link target=_blank}?

Зараз саме час використати його разом із FastAPI. 🚀

Раніше ми мали таку анотацію типу:

//// tab | Python 3.10+

```Python

            assertTrue(result.contains("errorCode=0x00000001") || result.contains("errorCode=1"));
        }

        @Test
        @DisplayName("Test toString with all command types")
        void testToStringAllCommands() {
            byte[] commands = { ServerMessageBlock.SMB_COM_CREATE_DIRECTORY, ServerMessageBlock.SMB_COM_DELETE_DIRECTORY,

Помните, я уже говорил, что `Annotated` можно использовать для добавления метаданных к параметрам в разделе [Введение в типы Python](../python-types.md#type-hints-with-metadata-annotations){.internal-link target=_blank}?

Пришло время использовать его с FastAPI. 🚀

У нас была такая аннотация типа:

//// tab | Python 3.10+

```Python
q: str | None = None

package jstream

import (
	"bytes"
	"encoding/json"
	"io"
	"strconv"
	"sync/atomic"
	"unicode/utf16"
)

// ValueType - defines the type of each JSON value
type ValueType int

// Different types of JSON value
const (
	Unknown ValueType = iota
	Null
	String
	Number
	Boolean
	Array
	Object
)

// MetaValue wraps a decoded interface value with the document

<h3 id="data-offsets">Interacting with Go types and constants</h3>

<p>
If a package has any .s files, then <code>go build</code> will direct
the compiler to emit a special header called <code>go_asm.h</code>,
which the .s files can then <code>#include</code>.
The file contains symbolic <code>#define</code> constants for the
offsets of Go struct fields, the sizes of Go struct types, and most

 * and data sources based on the configured crawling settings.
 *
 * <p>The job supports selective crawling by specifying configuration IDs for different
 * types of crawlers (web, file, data). It manages the crawler process lifecycle,
 * handles timeout scenarios, and ensures proper cleanup of resources.</p>

 * <p>Key features:</p>
