	Release()
}

type Data

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

Data is a reference counted byte buffer

func (*Data) Buf

func (d *Data) Buf() []byte

Buf returns the underlying buffer of the Data

func (*Data) Bytes

func (*Data) Truncate

func (d *Data) Truncate(n int) *Data

type RCBytes

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

RCBytes represents a reference counting data from cache it is immutable, caller should not modify it and call Release after use

func (RCBytes) Bytes

func (r RCBytes) Bytes() []byte

func (RCBytes) Release

func (r RCBytes) Release()

func (RCBytes) Slice

func (r RCBytes) Slice(n int) CacheData
