But you still need to define what is the dependable, the callable that you pass as a parameter to `Depends()` or `Security()`.

There are multiple tools that you can use to create those dependables, and they get integrated into OpenAPI so they are shown in the automatic docs UI, they can be used by automatically generated clients and SDKs, etc.

You can import them from `fastapi.security`:

```python
from fastapi.security import (

        flags &= ~flag;
    }

    /**
     * Sets a specific flag
     * @param flag the flag to set
     */
    public void setFlag(final int flag) {
        flags |= flag;
    }

    /**
     * Get the result of the DCERPC call.
     * @return result exception if the call failed, null otherwise
     */
    public DcerpcException getResult() {
        if (result != 0) {
            return new DcerpcException(result);

// blocks until the mutex is available.
func (lm *LRWMutex) Lock() {
	const isWriteLock = true
	lm.lockLoop(context.Background(), lm.id, lm.source, math.MaxInt64, isWriteLock)
}

// GetLock tries to get a write lock on lm before the timeout occurs.
func (lm *LRWMutex) GetLock(ctx context.Context, id string, source string, timeout time.Duration) (locked bool) {
	const isWriteLock = true

        return value(gitOrigin);
    }

    public static ZonedDateTime getBuildDate() {
        return value(buildDate);
    }

    public static BwcVersions getBwcVersions() {
        return value(bwcVersions).get();
    }

    public static String getTestSeed() {
        return value(testSeed);
    }

    public static Boolean isCi() {
        return value(isCi);
    }

                requestBody.put(idKey, setting.get(idKey));
            }

            final Map<String, Object> doc = new HashMap<>();
            doc.put("doc_id", setting.get("doc_id"));
            doc.put("url", setting.get("url_link"));
            doc.put("title", setting.get("title"));
            doc.put("role", "Rguest");
            doc.put("boost", setting.get("boost"));

   *  * The second race is between plan2 and plan3, with a 250 ms head start for plan2.
   *
   * We get plan0 and plan1 from the route planner.
   * We get plan2 as a follow-up to plan1, typically retry the same IP but different TLS.
   * We get plan3 as a retry of plan0, which was canceled when it lost the race.
