Types

type BufferedConn

type BufferedConn struct {
	net.Conn // So that most methods are embedded
	// contains filtered or unexported fields
}

BufferedConn provides an interface to peek at a connection

func (BufferedConn) Read

func (b BufferedConn) Read(p []byte) (int, error)

type Client

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

Client is a connection container

type Glutton

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