Overview

Package netx provides some convenient net functions.

Index

• func IPIsOn(ip string) (on bool, err error)
• func IsTimeout(err error) bool
• func SplitHostPort(hostport string) (host, port string)

Functions

func IPIsOn

func IPIsOn(ip string) (on bool, err error)

IPIsOn reports whether the ip is configured on a certain network interface.

If ip is empty, return (false, nil).

func IsTimeout

func IsTimeout(err error) bool

IsTimeout reports whether the error is timeout.

func SplitHostPort

func SplitHostPort(hostport string) (host, port string)

SplitHostPort separates host and port. If the port is not valid, it returns the entire input as host, and it doesn't check the validity of the host. Unlike net.SplitHostPort, but per RFC 3986, it requires ports to be numeric.
