What is the difference between tokio and tokio_core?
I am using tokio runtime and I need to use connect_stream from tokio_core so I am a bit confused

The tokio-core crate is a very very old and deprecated version of Tokio. The current version is tokio version 0.2.x.

If you're trying to create a Tokio TcpStream from a manually configured socket, the steps should be socket2::Socket::into_tcp_stream() → tokio::net::TcpStream::from_std(). Don't use tokio-core at all.
