type Cloud ¶

type Cloud struct {
	Client     *storage.Client
	BucketName string
}

Cloud is an implementation of DataStore using a Google Cloud Storage bucket.

func (s Cloud) Get(ctx context.Context, name string) ([]byte, error)

func (s Cloud) Has(ctx context.Context, name string) (bool, error)

func (s Cloud) Put(ctx context.Context, name string, value []byte) error

type DataStore ¶

type DataStore interface {
	Get(ctx context.Context, name string) ([]byte, error)
	Put(ctx context.Context, name string, value []byte) error
	// TODO: return size
	Has(ctx context.Context, name string) (bool, error)
}

DataStore is an interface defining low-level operations for handling unstructured key/value pairs. At this level, there is no concept of digest or any structure of the values.

type File ¶

type File struct {
	DirName string
}

File is an implementation of DataStore using the local file system, rooted at the specified directory.

func (s File) Get(ctx context.Context, name string) ([]byte, error)

func (s File) Has(ctx context.Context, name string) (bool, error)

func (s File) Put(ctx context.Context, name string, value []byte) error

type InMemory ¶

type InMemory struct {
	Inner map[string][]byte
}

func (s InMemory) Get(ctx context.Context, name string) ([]byte, error)

func (s InMemory) Has(ctx context.Context, name string) (bool, error)

func (s InMemory) Put(ctx context.Context, name string, value []byte) error

type Memcache ¶

type Memcache struct {
	Inner DataStore
	RDB   *redis.Client
}

func (s Memcache) Get(ctx context.Context, name string) ([]byte, error)

func (s Memcache) Has(ctx context.Context, name string) (bool, error)

func (s Memcache) Put(ctx context.Context, name string, value []byte) error

func (s Memcache) TrySet(ctx context.Context, name string, value []byte)
