Types

type Address

type Address interface {
	IP() net.IP        // IP of this Address
	Domain() string    // Domain of this Address
	Port() uint16      // Port of this Address
	PortBytes() []byte // Port in bytes, network byte order

	IsIPv4() bool   // True if this Address is an IPv4 address
	IsIPv6() bool   // True if this Address is an IPv6 address
	IsDomain() bool // True if this Address is an domain address

	String() string // String representation of this Address
}

Address represents a network address to be communicated with. It may be an IP address or domain address, not both. This interface doesn't resolve IP address for a given domain.

func DomainAddress

func DomainAddress(domain string, port uint16) Address

DomainAddress creates an Address with given domain and port.

func IPAddress

func IPAddress(ip []byte, port uint16) Address

IPAddress creates an Address with given IP and port.

type Destination

type Destination interface {
	Network() string  // Protocol of communication (tcp / udp)
	Address() Address // Address of destination
	String() string   // String representation of the destination

	IsTCP() bool // True if destination is reachable via TCP
	IsUDP() bool // True if destination is reachable via UDP
}

Destination represents a network destination including address and protocol (tcp / udp).

func NewTCPDestination

func NewTCPDestination(address Address) Destination

NewTCPDestination creates a TCP destination with given address

func NewUDPDestination

func NewUDPDestination(address Address) Destination

NewUDPDestination creates a UDP destination with given address
