I see we have std::net::tcp::TcpStream::set_nonblocking for setting this flag on a TcpStream instance.
If I have a TcpStream instance, and I want to read that flag (in my case, for the purpose of debugging), how would I do that?
In case this is platform specific, I'm targeting Linux.
I don't think that's exposed in the standard library but you can do it with socket2: SockRef in socket2 - Rust
That looks fine 
For debugging, i don't mind the extra dependency. Thank you!
