Types

type Keeper

type Keeper struct {
	porttypes.ICS4Wrapper
	vibctypes.ReceiverImpl
	// contains filtered or unexported fields
}

Keeper handles the interceptions from the vtransfer IBC middleware, passing them to the embedded vibc keeper if they involve a targeted address (which is an address associated with a VM listener). The embedded vibc keeper is used to bridge calls to swingset, but with a special wrapper on the bridge controller to use distinct action types. The keeper keeps a store of "targeted addresses", managed from Swingset by bridge messages.

func NewKeeper

func NewKeeper(
	cdc codec.Codec,
	key storetypes.StoreKey,
	prototypeVibcKeeper vibc.Keeper,
	scopedTransferKeeper capabilitykeeper.ScopedKeeper,
	pushAction vm.ActionPusher,
) Keeper

NewKeeper creates a new vtransfer Keeper instance

func (Keeper) GetICS4Wrapper

func (k Keeper) GetICS4Wrapper() porttypes.ICS4Wrapper

func (Keeper) GetReceiverImpl

func (k Keeper) GetReceiverImpl() vibctypes.ReceiverImpl

func (Keeper) GetWatchedAddresses

func (k Keeper) GetWatchedAddresses(ctx sdk.Context) ([]sdk.AccAddress, error)

GetWatchedAdresses returns the watched addresses from the keeper as a slice of account addresses.

func (Keeper) InterceptOnAcknowledgementPacket

func (k Keeper) InterceptOnAcknowledgementPacket(
	ctx sdk.Context,
	ibcModule porttypes.IBCModule,
	packet channeltypes.Packet,
	acknowledgement []byte,
	relayer sdk.AccAddress,
) error

InterceptOnAcknowledgementPacket checks to see if the packet sender is a targeted account, and if so, delegates to the VM.

func (Keeper) InterceptOnRecvPacket

func (k Keeper) InterceptOnRecvPacket(ctx sdk.Context, ibcModule porttypes.IBCModule, packet channeltypes.Packet, relayer sdk.AccAddress) ibcexported.Acknowledgement

InterceptOnRecvPacket runs the ibcModule and eventually acknowledges a packet. Many error acknowledgments are sent synchronously, but most cases instead return nil to tell the IBC system that acknowledgment is async (i.e., that WriteAcknowledgement will be called later, after the VM has dealt with the packet).

func (Keeper) InterceptOnTimeoutPacket

func (k Keeper) InterceptOnTimeoutPacket(
	ctx sdk.Context,
	ibcModule porttypes.IBCModule,
	packet channeltypes.Packet,
	relayer sdk.AccAddress,
) error

InterceptOnTimeoutPacket checks to see if the packet sender is a targeted account, and if so, delegates to the VM.

func (Keeper) InterceptWriteAcknowledgement

func (k Keeper) InterceptWriteAcknowledgement(ctx sdk.Context, chanCap *capabilitytypes.Capability, packet ibcexported.PacketI, ack ibcexported.Acknowledgement) error

InterceptWriteAcknowledgement checks to see if the packet's receiver is a targeted account, and if so, delegates to the VM.

func (Keeper) Receive

func (k Keeper) Receive(cctx context.Context, jsonRequest string) (jsonReply string, err error)

Receive implements the vm.PortHandler interface.

func (Keeper) SetWatchedAddresses

func (k Keeper) SetWatchedAddresses(ctx sdk.Context, addresses []sdk.AccAddress)

SetWatchedAddresses sets the watched addresses in the keeper from a slice of SDK account addresses.
