Types

type LaneState

type LaneState interface {
	Redeemed() (big.Int, error)
	Nonce() (uint64, error)
}

LaneState is an abstract copy of the state of a single lane

type MessageBuilder

type MessageBuilder interface {
	Create(to address.Address, initialAmount abi.TokenAmount) (*types.Message, error)
	Update(paych address.Address, voucher *SignedVoucher, secret []byte) (*types.Message, error)
	Settle(paych address.Address) (*types.Message, error)
	Collect(paych address.Address) (*types.Message, error)
}

func Message

func Message(version actors.Version, from address.Address) MessageBuilder

type ModVerifyParams

type ModVerifyParams = paych3.ModVerifyParams

type SignedVoucher

type SignedVoucher = paych3.SignedVoucher

type State interface {
	cbor.Marshaler
	// Channel owner, who has funded the actor
	From() (address.Address, error)
	// Recipient of payouts from channel
	To() (address.Address, error)

	// Height at which the channel can be `Collected`
	SettlingAt() (abi.ChainEpoch, error)

	// Amount successfully redeemed through the payment channel, paid out on `Collect()`
	ToSend() (abi.TokenAmount, error)

	// Get total number of lanes
	LaneCount() (uint64, error)

	// Iterate lane states
	ForEachLaneState(cb func(idx uint64, dl LaneState) error) error
}

State is an abstract version of payment channel state that works across versions

func Load

func Load(store adt.Store, act *types.Actor) (State, error)

Load returns an abstract copy of payment channel state, irregardless of actor version
