Perform a non-blocking connect to the given host and port see examples/echo_client.rb addr is a string, can be an IP address or a hostname.

Similar to .new, but used in cases where the resulting object is in a “half-open” state. This is primarily used for when asynchronous DNS resolution is taking place. We don't actually have a handle to the socket we want to use to create the watcher yet, since we don't know the IP address to connect to.
