 * This interface serves as the base for all Service Provider Interface (SPI) components in Maven.
 * Classes implementing this interface can be discovered and loaded by Maven through the
 * Java ServiceLoader mechanism, allowing plugins and extensions to contribute functionality
 * to the Maven build process.
 * <p>
 * SPI services are typically registered in {@code META-INF/services/} files corresponding to

 * of phases that can be executed during a build.
 * <p>
 * Implementations of this interface will be discovered through the Java ServiceLoader mechanism
 * and their provided lifecycles will be available throughout the Maven build process.
 * <p>
 * Example usage:
 * <pre>
 * public class CustomLifecycleProvider implements LifecycleProvider {

 * in different contexts, such as compilation, testing, or runtime.

 * Implementations of this interface will be discovered through the Java ServiceLoader mechanism

 * public class CustomPathScopeProvider implements PathScopeProvider {

 * Implementations of this interface will be discovered through the Java ServiceLoader mechanism

 * Example usage:
 * <pre>
 * public class CustomTypeProvider implements TypeProvider {

/**
 * Marker interface for objects that use the JVM's `synchronized` mechanism and the related
 * `wait()` and `notify()` functions.
 *
 * The Lockable interface is particularly handy because it ensures we lock the right `this` when
 * there are multiple `this` objects in scope.

### Technische Details: `root_path`

Wenn Sie eine Unteranwendung wie oben beschrieben mounten, kümmert sich FastAPI darum, den Mount-Pfad für die Unteranwendung zu kommunizieren, mithilfe eines Mechanismus aus der ASGI-Spezifikation namens `root_path`.

Auf diese Weise weiß die Unteranwendung, dass sie dieses Pfadpräfix für die Benutzeroberfläche der Dokumentation verwenden soll.

This would allow you to have a more fine-grained permission system, following the OAuth2 standard, integrated into your OpenAPI application (and the API docs).

OAuth2 with scopes is the mechanism used by many big authentication providers, like Facebook, Google, GitHub, Microsoft, X (Twitter), etc. They use it to provide specific permissions to users and applications.

deklariert wird, beispielsweise wenn mehrere Abhängigkeiten eine gemeinsame Unterabhängigkeit haben, wird **FastAPI** diese Unterabhängigkeit nur einmal pro Request aufrufen.

Und es speichert den zurückgegebenen Wert in einem <abbr title="Mechanismus, der bereits berechnete/generierte Werte zwischenspeichert, um sie später wiederzuverwenden, anstatt sie erneut zu berechnen.">„Cache“</abbr> und übergibt diesen gecachten Wert an alle „Dependanten“, die ihn in diesem spezifischen Request benötigen,...
