相当于Java的javax.net.ssl.SSLHandshakeException的Golang是什么？

I'm trying to set up some logging/monitoring for a Golang application. I want to be alerted if an SSL handshake error occurs. In Java I looked for the string "javax.net.ssl.SSLHandshakeException". Is there an equivalent in Golang for when something goes wrong with an SSL handshake?

Golang has no exceptions, but funcs return errors. This code would set err if the handshake fails:

conf := &tls.Config{}
tlsCon, err := tls.Dial("tcp", "example.com:443", conf)
if err != nil { // err is set when handshake fails
    fmt.Println(err.Error())
    return
}
tlsCon.Close()
