Types

type Factory

type Factory struct {
	ID string
}

Factory struct holds Storage.

func (*Factory) Storage

func (f *Factory) Storage() Storage

Storage method returns Storage.

type File

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

File represent a file as a storage.

func (*File) Init

func (f *File) Init(conf map[string]string) error

Init initialises the file storage.

func (*File) InitForFirstTime

func (f *File) InitForFirstTime(data []byte, conf map[string]string) error

InitForFirstTime initialises the file storage for the first time.

func (*File) Load

func (f *File) Load() ([]byte, error)

Load loads the file storage as a byte array.

func (*File) Store

func (f *File) Store(data []byte) error

Store store data in the file storage.

type GoogleDrive

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

GoogleDrive represent a GoogleDrive as a storage.

func (*GoogleDrive) Init

func (g *GoogleDrive) Init(conf map[string]string) error

Init initialises the storage. After "InitForFirstTime" method, this function can be called to initialize the GoogleDrive storage in the consequent uses.

func (*GoogleDrive) InitForFirstTime

func (g *GoogleDrive) InitForFirstTime(data []byte, conf map[string]string) error

InitForFirstTime initialises the GoogleDrive storage for the first time.

func (*GoogleDrive) Load

func (g *GoogleDrive) Load() ([]byte, error)

Load loads the GoogleDrive storage as a byte array.

func (*GoogleDrive) Store

func (g *GoogleDrive) Store(data []byte) error

Store store data in the GoogleDrive storage.

type Storage

type Storage interface {
	// InitForFirstTime initialises the storage for the first time.
	InitForFirstTime(data []byte, conf map[string]string) error

	// Init initialises the storage.
	// After "InitForFirstTime" method, this function can be called to initialize the storage in the consequent uses.
	Init(conf map[string]string) error

	// Load loads the storage as a byte array.
	Load() ([]byte, error)

	// Store store data in the storage.
	Store(data []byte) error
}

Storage interface is used to store data.
