Extensions
==========

SQLSpec extensions integrate the registry with frameworks and services such as
Litestar and Google ADK. Use these extensions for dependency injection, lifecycle
hooks, and application-facing helpers.

.. currentmodule:: sqlspec.extensions

Overview
========

- **Google ADK**: Session, event, and memory storage.
- **Litestar**: Plugin-based integration with dependency injection and lifecycle management.
- **FastAPI/Flask/Starlette/Sanic**: Framework helpers (see usage docs).

.. literalinclude:: /examples/extensions/adk/memory_store.py
   :language: python
   :caption: ``adk memory store``
   :start-after: # start-example
   :end-before: # end-example
