FilePiece
Concurrently read and write from files
Installation
go get storj.io/storj/pkg/filepiece
Usage
import "storj.io/storj/pkg/filepiece"
Chunk struct
type Chunk struct {
file *os.File
offset int64
length int64
currentPos int64
}
- Chunk.file - os.File being read from
- Chunk.offset - starting position for reading/writing data
- Chunk.length - length of data to be read/written
- Chunk.currentPos - Keeps track to know where to write to or read from next
NewChunk
Create a chunk from a file
func NewChunk(file *os.File, offset int64, length int64) (*Chunk, error)
Read
Concurrently read from a file
func (f *Chunk) Read(b []byte) (n int, err error)
func (f *Chunk) ReadAt(p []byte, off int64) (n int, err error)
Write
Concurrently write to a file
func (f *Chunk) Write(b []byte) (n int, err error)
func (f *Chunk) WriteAt(p []byte, off int64) (n int, err error)
Other
Get the size of the Chunk
func (f *Chunk) Size() int64
Close the Chunk File
func (f *Chunk) Close() error
Seek to certain position of Chunk
func (f *Chunk) Seek(offset int64, whence int) (int64, error)
