* single-element enum to maintain serialization guarantees. See Effective Java (2nd Edition), Item
 * 3: "Enforce the singleton property with a private constructor or an enum type". For example:

 * The <code>Secured</code> annotation is used to define a list of security configuration

 * For example:
 *
 * <pre>
 * &#064;Secured({ &quot;ROLE_USER&quot; })

`user_in`は`UserIn`クラスのPydanticモデルです。

Pydanticモデルには、モデルのデータを含む`dict`を返す`.dict()`メソッドがあります。

そこで、以下のようなPydanticオブジェクト`user_in`を作成すると:

```Python
user_in = UserIn(username="john", password="secret", email="john.doe@example.com")
```

そして呼び出すと:

```Python
user_dict = user_in.dict()
```

これで変数`user_dict`のデータを持つ`dict`ができました。（これはPydanticモデルのオブジェクトの代わりに`dict`です）。

そして呼び出すと:

```Python
print(user_dict)
```

 * <p><strong>Cycle Detection</strong>
 *
 * <p>Deadlocks can arise when locks are acquired in an order that forms a cycle. In a simple
 * example involving two locks and two threads, deadlock occurs when one thread acquires Lock A, and
 * then Lock B, while another thread acquires Lock B, and then Lock A:
 *
 * <pre>
 * Thread1: acquire(LockA) --X acquire(LockB)

    /**
     * Test constructor with raw bytes.
     */
    @Test
    public void testConstructorWithRawBytes() {
        byte[] rawBytes = new byte[8];
        SMBUtil.writeInt8(1234567890L, rawBytes, 0); // Example timestamp
        AvTimestamp avTimestamp = new AvTimestamp(rawBytes);

        assertNotNull(avTimestamp);
        assertEquals(AvPair.MsvAvTimestamp, avTimestamp.getType());

 * allowing for more precise control over which implementation should be injected.
 * Custom qualifier annotations should be annotated with {@code @Qualifier}.

 * Example of creating a custom qualifier:
 * <pre>
 * {@literal @}Qualifier

Якщо клієнт спробує надіслати **зайві** дані у **query параметрах**, він отримає **помилку**.

Наприклад, якщо клієнт спробує надіслати query параметр `tool` зі значенням `plumbus`, як у цьому запиті:

```http
https://example.com/items/?limit=10&tool=plumbus
```

Він отримає відповідь з **помилкою**, яка повідомить, що query параметр `tool ` не дозволено:

```json

MinIO needs a persistent volume to store configuration and application data. For testing purposes, you can launch MinIO by simply passing a directory (`/data` in the example below). This directory gets created in the container filesystem at the time of container start. But all the data is lost after container exits.

```sh
docker run \
  -p 9000:9000 \
  -p 9001:9001 \
