type Storer

type Storer interface {
	// IntervalChunks collects chunk for a requested interval.
	IntervalChunks(ctx context.Context, bin uint8, from, to uint64, limit int) (chunks []swarm.Address, topmost uint64, err error)

	Get(ctx context.Context, mode storage.ModeGet, addrs ...swarm.Address) ([]swarm.Chunk, error)
	// Put chunks.
	Put(ctx context.Context, mode storage.ModePut, chs ...swarm.Chunk) error
	// Set chunks.

	// Has chunks.
	Has(ctx context.Context, addr swarm.Address) (bool, error)
}
