How to get the tcp socket fd corresponding to the grpc channel

[venksj]

Hi,

I am new to hyperium/tonic. We are using tonic in our code to create a grpc channel.

Now, for scale testing, we want to plug this into a simulator. The simulator code is in C and it relies on polling on the underlying tcp socket. How can i retrieve the socket FD for the corresponding grpc channel?

regards!
