Types ¶

type Blockstore ¶

type Blockstore struct {
	dagstore.ReadBlockstore
	io.Closer
}

Blockstore promotes a dagstore.ReadBlockstore to a full closeable Blockstore, stubbing out the write methods with erroring implementations.

func (*Blockstore) DeleteBlock ¶

func (b *Blockstore) DeleteBlock(context.Context, cid.Cid) error

func (*Blockstore) Put ¶

func (b *Blockstore) Put(context.Context, blocks.Block) error

func (*Blockstore) PutMany ¶

func (b *Blockstore) PutMany(context.Context, []blocks.Block) error

type LotusMount ¶

type LotusMount struct {
	API      MinerAPI
	PieceCid cid.Cid
}

LotusMount is a DAGStore mount implementation that fetches deal data from a PieceCID.

func NewLotusMount ¶

func NewLotusMount(pieceCid cid.Cid, api MinerAPI) (*LotusMount, error)

func (*LotusMount) Close ¶

func (l *LotusMount) Close() error

func (*LotusMount) Fetch ¶

func (l *LotusMount) Fetch(ctx context.Context) (mount.Reader, error)

func (*LotusMount) Info ¶

func (l *LotusMount) Info() mount.Info

func (*LotusMount) Serialize ¶

type MinerAPI ¶

type MinerAPI interface {
	FetchUnsealedPiece(ctx context.Context, pieceCid cid.Cid) (mount.Reader, error)
	GetUnpaddedCARSize(ctx context.Context, pieceCid cid.Cid) (uint64, error)
	IsUnsealed(ctx context.Context, pieceCid cid.Cid) (bool, error)
	Start(ctx context.Context) error
}

func NewMinerAPI ¶

	UnsealSectorAt(ctx context.Context, sectorID abi.SectorNumber, pieceOffset abi.UnpaddedPieceSize, length abi.UnpaddedPieceSize) (mount.Reader, error)
}

type Wrapper ¶

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

func NewDAGStore ¶

func NewDAGStore(cfg config.DAGStoreConfig, minerApi MinerAPI, h host.Host) (*dagstore.DAGStore, *Wrapper, error)

func (*Wrapper) Close ¶

func (w *Wrapper) Close() error

func (*Wrapper) DestroyShard ¶
