	// ListStorageSpaces lists the spaces in the storage.
	// The unrestricted parameter can be used to list other user's spaces when
	// the user has the necessary permissions.
	ListStorageSpaces(ctx context.Context, filter []*provider.ListStorageSpacesRequest_Filter, unrestricted bool) ([]*provider.StorageSpace, error)
	CreateStorageSpace(ctx context.Context, req *provider.CreateStorageSpaceRequest) (*provider.CreateStorageSpaceResponse, error)

}

FS is the interface to implement access to the storage.

type PathWrapper

type PathWrapper interface {
	Unwrap(ctx context.Context, rp string) (string, error)
	Wrap(ctx context.Context, rp string) (string, error)
}

PathWrapper is the interface to implement for path transformations

type Registry

type Registry interface {
	// GetProvider returns the Address of the storage provider that should be used for the given space.
	// Use it to determine where to create a new storage space.
	GetProvider(ctx context.Context, space *provider.StorageSpace) (*registry.ProviderInfo, error)
	// ListProviders returns the storage providers that match the given filter
	ListProviders(ctx context.Context, filters map[string]string) ([]*registry.ProviderInfo, error)
}

Registry is the interface that storage registries implement for discovering storage providers
