Types ¶

type ErrPortAlreadyAllocated ¶

type ErrPortAlreadyAllocated struct {
	// contains filtered or unexported fields
}

func NewErrPortAlreadyAllocated ¶

func NewErrPortAlreadyAllocated(ip string, port int) ErrPortAlreadyAllocated

func (ErrPortAlreadyAllocated) Error ¶

func (e ErrPortAlreadyAllocated) Error() string

func (ErrPortAlreadyAllocated) IP ¶

func (e ErrPortAlreadyAllocated) IP() string

func (ErrPortAlreadyAllocated) IPPort ¶

func (e ErrPortAlreadyAllocated) IPPort() string

func (ErrPortAlreadyAllocated) Port ¶

func (e ErrPortAlreadyAllocated) Port() int

type PortAllocator ¶

type PortAllocator struct {
	Begin int
	End   int
	// contains filtered or unexported fields
}

func New ¶

func New() *PortAllocator

func (*PortAllocator) ReleaseAll ¶

func (p *PortAllocator) ReleaseAll() error

ReleaseAll releases all ports for all ips.

func (*PortAllocator) ReleasePort ¶

func (p *PortAllocator) ReleasePort(ip net.IP, proto string, port int) error

ReleasePort releases port from global ports pool for specified ip and proto.

func (*PortAllocator) RequestPort ¶

func (p *PortAllocator) RequestPort(ip net.IP, proto string, port int) (int, error)

RequestPort requests new port from global ports pool for specified ip and proto. If port is 0 it returns first free port. Otherwise it cheks port availability in pool and return that port or error if port is already busy.
