Functions

func CheckGetRaw 

func CheckGetRaw(raw *Raw, fileLength int64) error

CheckGetRaw check before get Raw

func CheckPutRaw 

func CheckPutRaw(raw *Raw) error

CheckPutRaw check before put Raw

func CheckTrunc 

func CheckTrunc(raw *Raw) error

CheckTrunc check before trunc file content

func Register 

func Register(name string, builder DriverBuilder)

func RegisterPlugin added in v2.0.2 

func RegisterPlugin(name string, builder DriverBuilder) error

RegisterPlugin defines an interface to register a driver with specified name. All drivers should call this function to register itself to the driverFactory.

Types

type Config 

type Config struct {
	BaseDir string `yaml:"baseDir"`
}

type Driver 

type Driver interface {

	// Get data from the storage based on raw information.
	// If the length<=0, the driver should return all data from the raw.offset.
	// Otherwise, just return the data which starts from raw.offset and the length is raw.length.
	Get(raw *Raw) (io.ReadCloser, error)

	// GetBytes data from the storage based on raw information.
	// The data should be returned in bytes.
	// If the length<=0, the storage driver should return all data from the raw.offset.
	// Otherwise, just return the data which starts from raw.offset and the length is raw.length.
	GetBytes(raw *Raw) ([]byte, error)

	// Put the data into the storage with raw information.
	// The storage will get data from io.Reader as io stream.
	// If the offset>0, the storage driver should starting at byte raw.offset off.
	Put(raw *Raw, data io.Reader) error

	// PutBytes puts the data into the storage with raw information.
	// The data is passed in bytes.
	// If the offset>0, the storage driver should starting at byte raw.offset off.
	PutBytes(raw *Raw, data []byte) error

	// Remove the data from the storage based on raw information.
	Remove(raw *Raw) error

	// Stat determines whether the data exists based on raw information.
	// If that, and return some info that in the form of struct StorageInfo.
	// If not, return the ErrFileNotExist.
	Stat(raw *Raw) (*StorageInfo, error)

	// GetFreeSpace returns the free disk space in B.
	GetFreeSpace() (unit.Bytes, error)

	// GetTotalAndFreeSpace returns the total and free disk space in B.
	GetTotalAndFreeSpace() (unit.Bytes, unit.Bytes, error)

	// GetTotalSpace returns the total disk space in B.
	GetTotalSpace() (unit.Bytes, error)

	// Walk walks the file tree rooted at root which determined by raw.Bucket and raw.Key,
	// calling walkFn for each file or directory in the tree, including root.
	Walk(raw *Raw) error

	// CreateBaseDir create base dir
	CreateBaseDir() error

	// GetPath get path of raw
	GetPath(raw *Raw) string

	// MoveFile rename src to dst
	MoveFile(src string, dst string) error

	// Exits check if raw exists
	Exits(raw *Raw) bool

	// GetBaseDir returns base dir
	GetBaseDir() string
}

Driver defines an interface to manage the data stored in the driver.

NOTE: It is recommended that the lock granularity of the driver should be in piece. That means that the storage driver could read and write the different pieces of the same file concurrently.

func Get 

func Get(name string) DriverBuilder

Get return a storage manager from manager with specified name.
