Functions

func TCP6Enabled

func TCP6Enabled() bool

TCP6Enabled returns true if dialing and listening for IPv4 TCP is enabled.

Types

type ConnPool

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

ConnPool is a connection pool with ZSTD-compressed connections.

func NewConnPool

func NewConnPool(name, addr string, handshakeFunc handshake.Func, compressionLevel int) *ConnPool

NewConnPool creates a new connection pool for the given addr.

Name is used in exported metrics. handshakeFunc is used for handshaking after the connection establishing. The compression is disabled if compressionLevel <= 0.

func (*ConnPool) Addr

func (cp *ConnPool) Addr() string

Addr returns the address where connections are established.

func (*ConnPool) Get

func (cp *ConnPool) Get() (*handshake.BufferedConn, error)

Get returns free connection from the pool.

func (*ConnPool) Put

func (cp *ConnPool) Put(bc *handshake.BufferedConn)

Put puts bc back to the pool.

Do not put broken and closed connections to the pool!

type TCPDialer

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

TCPDialer is used for dialing the addr passed to NewTCPDialer.

It also gathers various stats for dialed connections.

func NewTCPDialer

func NewTCPDialer(name, addr string) *TCPDialer

NewTCPDialer returns new dialer for dialing the given addr.

The name is used in metric tags for the returned dialer. The name must be unique among dialers.

func (*TCPDialer) Addr

func (d *TCPDialer) Addr() string

Addr returns the address the dialer dials to.

func (*TCPDialer) Dial

func (d *TCPDialer) Dial() (net.Conn, error)

Dial dials the addr passed to NewTCPDialer.

type TCPListener

type TCPListener struct {
	net.Listener
	// contains filtered or unexported fields
}

TCPListener listens for the addr passed to NewTCPListener.

It also gathers various stats for the accepted connections.

func NewTCPListener

func NewTCPListener(name, addr string) (*TCPListener, error)

NewTCPListener returns new TCP listener for the given addr.

name is used for exported metrics. Each listener in the program must have distinct name.

func (*TCPListener) Accept

func (ln *TCPListener) Accept() (net.Conn, error)

Accept accepts connections from the addr passed to NewTCPListener.
