type DiffDealStatesFunc func(ctx context.Context, oldDealStateRoot, newDealStateRoot market.DealStates) (changed bool, user UserData, err error)

type DiffInitActorStateFunc

type DiffInitActorStateFunc func(ctx context.Context, oldState init_.State, newState init_.State) (changed bool, user UserData, err error)

type DiffMinerActorStateFunc

type DiffMinerActorStateFunc func(ctx context.Context, oldState miner.State, newState miner.State) (changed bool, user UserData, err error)

type DiffPaymentChannelStateFunc

type DiffPaymentChannelStateFunc func(ctx context.Context, oldState paych.State, newState paych.State) (changed bool, user UserData, err error)

DiffPaymentChannelStateFunc is function that compares two states for the payment channel

type DiffStorageMarketStateFunc

type DiffStorageMarketStateFunc func(ctx context.Context, oldState market.State, newState market.State) (changed bool, user UserData, err error)

type DiffTipSetKeyFunc

type DiffTipSetKeyFunc func(ctx context.Context, oldState, newState types.TipSetKey) (changed bool, user UserData, err error)

DiffTipSetKeyFunc check if there's a change form oldState to newState, and returns - changed: was there a change - user: user-defined data representing the state change - err
