fastapi/applications.py:1070–1103

Generate the OpenAPI schema of the application. This is called by FastAPI internally. The first time it is called it stores the result in the attribute `app.openapi_schema`, and next times it is called, it just returns that same result. To avoid the cost of

(self)

        return app
