) (big.Int, big.Int, uint64, error)

	SectorExpiry abi.ChainEpoch
}

type Actor 

type Actor struct{}

func (Actor) ActivateDeals 

func (a Actor) ActivateDeals(rt Runtime, params *ActivateDealsParams) *abi.EmptyValue

Verify that a given set of storage deals is valid for a sector currently being ProveCommitted, update the market's internal state accordingly.

func (Actor) AddBalance

Deposits the received value into the balance held in escrow.

func (Actor) Code 

func (a Actor) Code() cid.Cid

func (Actor) ComputeDataCommitment 

func (a Actor) ComputeDataCommitment(rt Runtime, params *ComputeDataCommitmentParams) *cbg.CborCid

func (Actor) Constructor 

func (a Actor) Constructor(rt Runtime, _ *abi.EmptyValue) *abi.EmptyValue

This method performs some light validation on the way in order to fail early if deals can be determined to be invalid for the proposed sector properties. Full deal validation is deferred to deal activation since it depends on the activation epoch.

Note: Deal Collateral is only released and returned to clients and miners when the storage deal stops counting towards power. In the current iteration, it will be released when the sector containing the storage deals expires, even though some storage deals can expire earlier than the sector does. Collaterals are denominated in PerEpoch to incur a cost for self dealing or minimal deals that last for a long time. Note: ClientCollateralPerEpoch may not be needed and removed pending future confirmation. There will be a Minimum value for both client and provider deal collateral.
