Overview ¶
Package reuseport provides Listen and Dial functions that set socket options in order to be able to reuse ports. You should only use this package if you know what SO_REUSEADDR and SO_REUSEPORT are.
For example:
// listen on the same port. oh yeah.
l1, _ := reuse.Listen("tcp", "127.0.0.1:1234")
l2, _ := reuse.Listen("tcp", "127.0.0.1:1234")
// dial from the same port. oh yeah.
l1, _ := reuse.Listen("tcp", "127.0.0.1:1234")
l2, _ := reuse.Listen("tcp", "127.0.0.1:1235")
c, _ := reuse.Dial("tcp", "127.0.0.1:1234", "127.0.0.1:1235")
Note: cant dial self because tcp/ip stacks use 4-tuples to identify connections, and doing so would clash.

Functions ¶
func Available ¶
func Available() bool
Available returns whether or not SO_REUSEPORT or equivalent behaviour is available in the OS.
func Dial ¶
Dial dials the given network and address. see net.Dial Returns a net.Conn created from a file descriptor for a socket with SO_REUSEPORT and SO_REUSEADDR option set.
func DialTimeout ¶
Dial dials the given network and address, with the given timeout. see net.DialTimeout Returns a net.Conn created from a file descriptor for a socket with SO_REUSEPORT and SO_REUSEADDR option set.
func Listen ¶
Listen listens at the given network and address. see net.Listen Returns a net.Listener created from a file discriptor for a socket with SO_REUSEPORT and SO_REUSEADDR option set.
func ListenPacket ¶
func ListenPacket(network, address string) (net.PacketConn, error)
ListenPacket listens at the given network and address. see net.ListenPacket Returns a net.Listener created from a file discriptor for a socket with SO_REUSEPORT and SO_REUSEADDR option set.
