Functions

func Sort

func Sort(ids []uint32)

Types

type Compressor

type Compressor interface {
	// 将整型切片压缩成二进制字节切片
	Marshal(ids []uint32) (ret []byte)
	// 将二进制字节切片反序列化为整型切片
	// 反序列化后得到的整型切片，切片中整型的顺序和序列化之前保持不变
	Unmarshal(b []byte) (ids []uint32)
}

具体使用见 LFCompressor 和 OriginCompressor

type LFCompressor

type LFCompressor struct {
	FB      uint32 // 用几个字节的 bit 表示跟随的数据
	ZlibExt bool   // 压缩之后，是否再用 zlib 进一步压缩
	// contains filtered or unexported fields
}

func (*LFCompressor) Marshal

func (lfc *LFCompressor) Marshal(ids []uint32) (ret []byte)

传入的整型切片必须是从小到大有序排列

func (*LFCompressor) Unmarshal

func (lfc *LFCompressor) Unmarshal(b []byte) (ids []uint32)

type OriginCompressor

type OriginCompressor struct {
	ZlibExt bool // 压缩之后，是否再用 zlib 进一步压缩
}

func (*OriginCompressor) Marshal

func (oc *OriginCompressor) Marshal(ids []uint32) (ret []byte)

并不强制要求整型切片有序

func (*OriginCompressor) Unmarshal

func (oc *OriginCompressor) Unmarshal(b []byte) (ids []uint32)
