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

Buffer provides in-memory buffer optimized for storing big bytes volumes.

It stores the data in chunks of fixed size. This reduces memory fragmentation and memory waste comparing to the contiguous slices of bytes.

func (cb *Buffer) Len() int

Len returns the length of the data stored at cb.

func (cb *Buffer) MustClose()

MustClose closes cb for subsequent reuse.

func (cb *Buffer) MustReadAt(p []byte, off int64)

MustReadAt reads len(p) bytes from cb at the offset off.

func (cb *Buffer) MustWrite(p []byte)

MustWrite writes p to cb.

func (cb *Buffer) NewReader() filestream.ReadCloser

NewReader returns a reader for reading the data stored in cb.

func (cb *Buffer) Path() string

Path returns cb path.

func (cb *Buffer) Reset()

Reset resets the cb, so it can be reused for writing new data into it.

Reset frees up memory chunks allocated for cb, so they could be reused by other Buffer instances.

func (cb *Buffer) SizeBytes() int

SizeBytes returns the number of bytes occupied by the cb.

func (cb *Buffer) Write(p []byte) (int, error)

Write implements io.Writer interface for cb.

func (cb *Buffer) WriteTo(w io.Writer) (int64, error)

WriteTo writes cb data to w.
