Why not use eprintln! for error handling?

[ghost]

E.g., https://docs.rs/tokio/latest/tokio/net/struct.TcpListener.html The error handling uses println!("couldn't get client: {:?}", e) , but it will be printed to standard output. Eprintln prints to standard error.

It's just an example. There isn't any reason.

Feel free to change it, though. I think a PR to switch to eprintln is reasonable personally.
