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.

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'79((5'48889hhugt,,,99,s:1BA6 A4 A6B.B/B4A66A?;BN)__name__ __module__ __qualname____doc__r rrr r rrs-D-r rN)rrrr r rs@$-$-r
