Functions

func Delete

func Delete(s storage.IndexStore, scope string, addr swarm.Address, batchId []byte) error

Delete removes a stamp associated with an chunk and batchID.

func DeleteAll

func DeleteAll(s storage.IndexStore, scope string, addr swarm.Address) error

DeleteAll removes all swarm.Stamp related to the given address.

func DeleteWithStamp

func DeleteWithStamp(
	writer storage.Writer,
	scope string,
	addr swarm.Address,
	stamp swarm.Stamp,
) error

func Load

func Load(s storage.Reader, scope string, addr swarm.Address) (swarm.Stamp, error)

Load returns first found swarm.Stamp related to the given address.

func LoadWithBatchID

func LoadWithBatchID(s storage.Reader, scope string, addr swarm.Address, batchID []byte) (swarm.Stamp, error)

LoadWithBatchID returns swarm.Stamp related to the given address and batchID.

func Store

func Store(s storage.IndexStore, scope string, chunk swarm.Chunk) error

Store creates new or updated an existing stamp index record related to the given scope and chunk.

Types

type Item

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

Item is the index used to represent a stamp for a chunk.

Going ahead we will support multiple stamps on chunks. This Item will allow mapping multiple stamps to a single address. For this reason, the address is part of the Namespace and can be used to iterate on all the stamps for this address.

func (*Item) Clone

func (i *Item) Clone() storage.Item

Clone implements the storage.Item interface.

func (*Item) ID

func (i *Item) ID() string

ID implements the storage.Item interface.

func (*Item) Marshal

func (i *Item) Marshal() ([]byte, error)

Marshal implements the storage.Item interface. address is not part of the payload which is stored, as address is part of the prefix, hence already known before querying this object. This will be reused during unmarshaling.

func (*Item) Namespace

func (i *Item) Namespace() string

Namespace implements the storage.Item interface.

func (*Item) SetScope

func (i *Item) SetScope(ns []byte)

func (Item) String

func (i Item) String() string

String implements the storage.Item interface.

func (*Item) Unmarshal

func (i *Item) Unmarshal(bytes []byte) error

Unmarshal implements the storage.Item interface.
