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

Args: scope: A dict containing ASGI connection scope. receive (callable): An awaitable callable for receiving ASGI events. send (callable): 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)dictr r )r rreceivesendrs r __call__TracingMiddleware.__call__s =F "yE'95+,G!W,''w'7((548888hhut,,,987,s:3B A6 A4 A6B .B/B 4A66 BB )r r N) __name__ __module__ __qualname____firstlineno____doc__r rr__static_attributes__rr rrs -D-rrN)rrr!rr r"s@&-&-r
