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 )r rreceivesendrs r __call__zTracingMiddleware.__call__s =F "yE'95+,G!W,''w'7((5'48888hhugt,,,98,s:1BA6 A4 A6B.B/B4A66A?;BN)__name__ __module__ __qualname____doc__r rrr r rrs -D-r rN)rrrr r rs@&-&-r
