///

The `oauth2_scheme` variable is an instance of `OAuth2PasswordBearer`, but it is also a "callable".

It could be called as:

```Python
oauth2_scheme(some, parameters)
```

So, it can be used with `Depends`.

### Use it

from collections import deque
from copy import copy
from dataclasses import dataclass, is_dataclass
from enum import Enum
from functools import lru_cache
from typing import (
    Any,
    Callable,
    Deque,
    Dict,
    FrozenSet,
    List,
    Mapping,
    Sequence,
    Set,
    Tuple,
    Type,
    Union,
)

from fastapi.exceptions import RequestErrorModel
from fastapi.types import IncEx, ModelNameMap, UnionType

            Callable<T> supplier) {
        Supplier<T> s = asSupplier(supplier);
        if (cache == null) {
            return s.get();
        } else {
            return cache.computeIfAbsent(groupId, artifactId, version, tag.getName(), s);
        }
    }

    private static <T> T cache(ModelCache cache, Source source, ModelCacheTag<T> tag, Callable<T> supplier) {

    assertEquals(key, result.get(0));
    assertEquals(key, result.get(1));
    assertEquals(key + suffix, cache.getUnchecked(key));
  }

  static <T> Callable<T> throwing(final Exception exception) {
    return new Callable<T>() {
      @Override
      public T call() throws Exception {
        throw exception;
      }
    };
  }

A variável `oauth2_scheme` é um instância de `OAuth2PasswordBearer`, mas também é um "callable".

Pode ser chamada de:

```Python
oauth2_scheme(some, parameters)
```

Então, pode ser usado com `Depends`.

## Use-o
