Convert String to SocketAddr

Question

In versions of Rust before 1.0, I was able to use from_str() to convert a String to SocketAddr, but that function no longer exists. How ca

I'll expand on "if you want to connect right away" comment in Shepmaster's answer.

Note that you don't really need to convert a string to a SocketAddr in advance in order to connect to something. TcpStream::connect() and other functions which take addresses are defined to accept an instance of ToSocketAddr trait:

fn connect(addr: T) -> TcpStream { ... }

It means that you can just pass a string to connect() without any conversions:

TcpStream::connect("stackoverflow.com:80")

Moreover, it is better not to convert the string to the SocketAddr in advance because domain names can resolve to multiple addresses, and TcpStream has special logic to handle this.
