Types

type Module

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

Module exposes storage and monitoring from the market.

func New

func New(ds datastore.TxnDatastore, clientBuilder lotus.ClientBuilder, pollDuration time.Duration, dealFinalityTimeout time.Duration, opts ...deals.Option) (*Module, error)

New creates a new Module.

func (*Module) CalculateDealPiece

func (m *Module) CalculateDealPiece(ctx context.Context, c cid.Cid) (api.DataCIDSize, error)

CalculateDealPiece calculates the size and CommP for a data cid.

func (*Module) Fetch

func (m *Module) Fetch(ctx context.Context, waddr string, payloadCid cid.Cid, pieceCid *cid.Cid, miners []string) (string, <-chan marketevents.RetrievalEvent, error)

Fetch fetches deal data to the underlying blockstore of the Filecoin client. This API is meant for clients that use external implementations of blockstores with their own API, e.g: IPFS.

func (*Module) GetDealInfo

func (m *Module) GetDealInfo(ctx context.Context, dealID uint64) (api.MarketDeal, error)

GetDealInfo returns info about a deal. If the deal isn't active on-chain, it returns ErrDealNotFound.

func (*Module) Import

func (m *Module) Import(ctx context.Context, data io.Reader, isCAR bool) (cid.Cid, int64, error)

Import imports raw data in the Filecoin client. The isCAR flag indicates if the data is already in CAR format, so it shouldn't be encoded into a UnixFS DAG in the Filecoin client. It returns the imported data cid and the data size.

func (*Module) ListRetrievalDealRecords

func (m *Module) ListRetrievalDealRecords(opts ...deals.DealRecordsOption) ([]deals.RetrievalDealRecord, error)

ListRetrievalDealRecords returns a list of retrieval deals according to the provided options.

func (*Module) ListStorageDealRecords

func (m *Module) ListStorageDealRecords(opts ...deals.DealRecordsOption) ([]deals.StorageDealRecord, error)

ListStorageDealRecords lists storage deals according to the provided options.

func (*Module) Retrieve

func (m *Module) Retrieve(ctx context.Context, waddr string, payloadCid cid.Cid, pieceCid *cid.Cid, miners []string, CAREncoding bool) (string, io.ReadCloser, error)

Retrieve retrieves Deal data. It returns the miner address where the data is being fetched from, and a byte reader to read the retrieved data.

func (*Module) Store

func (m *Module) Store(ctx context.Context, waddr string, dataCid cid.Cid, pieceSize abi.PaddedPieceSize, pieceCid cid.Cid, dcfgs []deals.StorageDealConfig, minDuration uint64) ([]deals.StoreResult, error)

Store create Deal Proposals with all miners indicated in dcfgs. The epoch price is automatically calculated considering each miner epoch price and piece size. The data of dataCid should be already imported to the Filecoin Client or should be accessible to it. (e.g: is integrated with an IPFS node).

func (*Module) Watch

func (m *Module) Watch(ctx context.Context, proposals []cid.Cid) (<-chan deals.StorageDealInfo, error)

Watch returns a channel with state changes of indicated proposals.
