func (c *Client) DialAndAuth(brokerAddress string) (net.Conn, error)

func (*Client) Run

func (c *Client) Run(connSrc <-chan Conn) error

Run causes the client to start waiting for new connections to connSrc and proxy them to the destination instance. It blocks until connSrc is closed.

type Conn

type Conn struct {
	BrokerAddress   string
	LocalConnection net.Conn
}

Conn represents a connection from a client to a specific instance.

type ConnSet

type ConnSet struct {
	sync.RWMutex
	// contains filtered or unexported fields
}

A ConnSet tracks net.Conns associated with a provided ID.

func NewConnSet

func NewConnSet() *ConnSet

NewConnSet initializes a new ConnSet and returns it.

func (*ConnSet) Add

func (c *ConnSet) Add(id string, conn net.Conn)

Add saves the provided conn and associates it with the given string identifier.

func (*ConnSet) Close

func (c *ConnSet) Close() error

Close closes every net.Conn contained in the set.

func (*ConnSet) Conns

func (c *ConnSet) Conns(ids ...string) []net.Conn

Conns returns all active connections associated with the provided ids.

func (*ConnSet) Count

func (c *ConnSet) Count() map[string]int

Count returns number of connection pro identifier

func (*ConnSet) IDs

func (c *ConnSet) IDs() []string

IDs returns a slice of all identifiers which still have active connections.

func (*ConnSet) Remove

func (c *ConnSet) Remove(id string, conn net.Conn) error

Remove undoes an Add operation to have the set forget about a conn. Do not Remove an id/conn pair more than it has been Added.

func (*ConnSet) String

func (c *ConnSet) String() string

String returns a debug string for the ConnSet.
