You could also use `from starlette.staticfiles import StaticFiles`.

**FastAPI** provides the same `starlette.staticfiles` as `fastapi.staticfiles` just as a convenience for you, the developer. But it actually comes directly from Starlette.

You can also use Pydantic models as subtypes of `list`, `set`, etc.:

{* ../../docs_src/body_nested_models/tutorial006_py310.py hl[18] *}

This will expect (convert, validate, document, etc.) a JSON body like:

  <name>Guava ListenableFuture only</name>
  <description>
    An empty artifact that Guava depends on to signal that it is providing
    ListenableFuture -- but is also available in a second "version" that
    contains com.google.common.util.concurrent.ListenableFuture class, without
    any other Guava classes. The idea is:

 * Implementations of this interface should provide the logic for reading
 * documents and converting them into a key-value structure.
 *
 * <p>This interface extends {@link java.io.Closeable}, so implementations
 * should also handle resource cleanup when the {@link #close()} method is called.</p>
 */
public interface DocumentReader extends Closeable {
    /**
     * Reads a document and returns its contents as a map.
     *

        self.name = name


fluffy = Cat(name="Mr Fluffy")
```

In this case, `fluffy` is an instance of the class `Cat`.

And to create `fluffy`, you are "calling" `Cat`.

So, a Python class is also a **callable**.

Then, in **FastAPI**, you could use a Python class as a dependency.

What FastAPI actually checks is that it is a "callable" (function, class or anything else) and the parameters defined.

#### Secret Keys

The MinIO server uses a unique, randomly generated secret key per object also known as, Object Encryption Key ([OEK](#oek)). Neither the client-provided SSE-C key nor the KMS-managed key is directly used to en/decrypt an object. Instead, the OEK is stored as part of the object metadata next to the object in an encrypted form. To en/decrypt the OEK another secret key is needed also known as, Key Encryption Key ([KEK](#kek)).
