This middleware checks for the 'langsmith-trace' header and propagates the tracing context if present. It does not start new traces by default. It is designed to work with ASGI applications.

Args: scope: A dict containing ASGI connection scope. receive: An awaitable callable for receiving ASGI events. send: An awaitable callable for sending ASGI events. If the request is HTTP and contains the 'langsmith-trace' header, it propagates the tracing context before calling the wrapped application. Otherwise, it calls the application directly without modifying the context. typehttpheadersslangsmith-trace)parentN)dictrr)rr Zreceivesendr rrr__call__s  2zTracingMiddleware.__call__N)__name__ __module__ __qualname____doc__r rrrrrrrs rN)rrrrrrs
