Types

type Storage

type Storage interface {
	// Get returns an io.ReadCloser for data at path, namespaced to the
	// model.
	//
	// If the data is still being uploaded and is not fully written yet, a
	// blobstore.ErrUploadPending error is returned. This means the path is
	// valid but the caller should try again later to retrieve the data.
	Get(path string) (r io.ReadCloser, length int64, err error)

	// Put stores data from reader at path, namespaced to the model.
	Put(path string, r io.Reader, length int64) error

	// PutAndCheckHash stores data from reader at path, namespaced to
	// the model. It also ensures the stored data has the correct
	// hash.
	PutAndCheckHash(path string, r io.Reader, length int64, hash string) error

	// Remove removes data at path, namespaced to the model.
	Remove(path string) error
