type Buffer struct {
	Buf []byte // 应用内缓存区
	// contains filtered or unexported fields
}

buffer 读缓冲区,每个tcp长连接对应一个读缓冲区

func NewBuffer(bytes []byte) *Buffer

NewBuffer 创建一个缓存区

func (b *Buffer) Len() int

func (b *Buffer) Read(offset, limit int) ([]byte, error)

Read 舍弃offset个字段，读取n个字段,如果没有足够的字节，返回错误

func (b *Buffer) ReadFromFD(fd int) error

ReadFromFD 从文件描述符里面读取数据

func (b *Buffer) ReadFromReader(reader io.Reader) (int, error)

ReadFromReader 从reader里面读取数据，如果reader阻塞，会发生阻塞

func (b *Buffer) Seek(len int) ([]byte, error)

Seek 返回n个字节，而不产生移位，如果没有足够字节，返回错误

type Event struct {
	Fd   int32 // 文件描述符
	Type int32 // 事件类型
}

func (e *Event) Fmt(flag string) string

type Logger interface {
