Functions

func GenerateCommP

func GenerateCommP(filepath string) (cidAndSize *writer.DataCIDSize, finalErr error)

GenerateCommP

func GeneratePieceCommitment

func GeneratePieceCommitment(filepath string, dealSize abi.PaddedPieceSize) (c cid.Cid, finalErr error)

GeneratePieceCommitment generates the pieceCid for the CARv1 deal payload in the CARv2 file that already exists at the given path.

Types

type ChainDealManager

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

func NewChainDealManager

func NewChainDealManager(a v1api.FullNode, cfg ChainDealManagerCfg) *ChainDealManager

func (*ChainDealManager) CheckDealEquality

func (c *ChainDealManager) CheckDealEquality(ctx context.Context, tok ctypes.TipSetKey, p1, p2 market.DealProposal) (bool, error)

func (*ChainDealManager) GetCurrentDealInfo

func (c *ChainDealManager) GetCurrentDealInfo(ctx context.Context, tok ctypes.TipSetKey, proposal *market.DealProposal, publishCid cid.Cid) (CurrentDealInfo, error)

GetCurrentDealInfo gets the current deal state and deal ID. Note that the deal ID is assigned when the deal is published, so it may have changed if there was a reorg after the deal was published.

func (c *ChainDealManager) WaitForPublishDeals(ctx context.Context, publishCid cid.Cid, proposal market8.DealProposal) (*storagemarket.PublishDealsWaitResult, error)

type ChainDealManagerCfg

type ChainDealManagerCfg struct {
	PublishDealsConfidence uint64
}

type Config

type Config struct {
	// The maximum amount of time a transfer can take before it fails
	MaxTransferDuration time.Duration
}

type CurrentDealInfo

type CurrentDealInfo struct {
	DealID           abi.DealID
	MarketDeal       *api.MarketDeal
	PublishMsgTipSet ctypes.TipSetKey
}

type Provider

type Provider struct {

	// Address of the provider on chain.
	Address address.Address

	Transport transport.Transport
	// contains filtered or unexported fields
}
