Functions

func ReadNum

func ReadNum(r io.Reader) (n uint32, cnt uint32, err error)

func WriteNum

func WriteNum(w io.Writer, n uint32) (cnt uint32, err error)

Types

type Constructor

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

func NewWriter

func NewWriter(buf []byte) (c Constructor)

NewWriter 新的写入构造器

func (*Constructor) Cap

func (c *Constructor) Cap() uint32

Cap structlen 目前写入的总长, 带 padding

func (*Constructor) Len

func (c *Constructor) Len() uint32

Len reallen 目前写入的实值总长, 不带 padding

func (*Constructor) WriteString

func (c *Constructor) WriteString(s string, cap uint32) error

WriteString 按字符串写入一项

func (*Constructor) WriteTo

func (c *Constructor) WriteTo(w io.Writer) (int64, error)

WriteTo 将当前结果写出, 返回写入的实际长度

type Iterator

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

func NewReader

func NewReader(r io.Reader) (it Iterator, err error)

NewReader 迭代器形式读取而非一次解析完

func (*Iterator) Bytes

func (it *Iterator) Bytes() []byte

Bytes 本次迭代的原始值

func (*Iterator) Cap

func (it *Iterator) Cap() uint32

Cap structlen 结构体带 padding 的长度

func (*Iterator) Len

func (it *Iterator) Len() uint32

Len reallen (迭代器目前迭代到的实值总长, 不带 padding)

func (*Iterator) Next

func (it *Iterator) Next() bool

Next 是否有下一个

func (*Iterator) String

func (it *Iterator) String() string

String 将本次迭代的值解释为 string

type SimplePB

type SimplePB struct {
	StructLen, RealLen uint32
	Target             [][]byte
}

func NewSimplePB

func NewSimplePB(r io.Reader) (s SimplePB, err error)
