Functions ¶

func EgressKey ¶

func EgressKey(destChain string, index int64) []byte

Stores an outgoing IBC packet under "egress/chain_id/index".

func EgressLengthKey ¶

func EgressLengthKey(destChain string) []byte

Stores the number of outgoing IBC packets under "egress/index".

func ErrIdenticalChains ¶

func ErrIdenticalChains() sdk.Error

func ErrInvalidSequence ¶

func ErrInvalidSequence() sdk.Error

func IngressSequenceKey ¶

func IngressSequenceKey(srcChain string) []byte

Stores the sequence number of incoming IBC packet under "ingress/index".

func NewHandler ¶

func NewHandler(ibcm IBCMapper, ck bank.CoinKeeper) sdk.Handler

Types ¶

type IBCMapper ¶

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

func NewIBCMapper ¶

func NewIBCMapper(cdc *wire.Codec, key sdk.StoreKey) IBCMapper

XXX: The IBCMapper should not take a CoinKeeper. Rather have the CoinKeeper take an IBCMapper.

func (IBCMapper) GetIngressSequence ¶

func (ibcm IBCMapper) GetIngressSequence(ctx sdk.Context, srcChain string) int64

func (IBCMapper) PostIBCPacket ¶

func (ibcm IBCMapper) PostIBCPacket(ctx sdk.Context, packet IBCPacket) sdk.Error

XXX: This is not the public API. This will change in MVP2 and will henceforth only be invoked from another module directly and not through a user transaction. TODO: Handle invalid IBC packets and return errors.

func (IBCMapper) ReceiveIBCPacket ¶

func (ibcm IBCMapper) ReceiveIBCPacket(ctx sdk.Context, packet IBCPacket) sdk.Error

XXX: In the future every module is able to register it's own handler for handling it's own IBC packets. The "ibc" handler will only route the packets to the appropriate callbacks. XXX: For now this handles all interactions with the CoinKeeper. XXX: This needs to do some authentication checking.

func (IBCMapper) SetIngressSequence ¶

func (ibcm IBCMapper) SetIngressSequence(ctx sdk.Context, srcChain string, sequence int64)

type IBCPacket ¶

type IBCPacket struct {
	SrcAddr   sdk.Address
	DestAddr  sdk.Address
	Coins     sdk.Coins
	SrcChain  string
	DestChain string
}

IBCPacket defines a piece of data that can be send between two separate blockchains.

func NewIBCPacket ¶

func NewIBCPacket(srcAddr sdk.Address, destAddr sdk.Address, coins sdk.Coins,
	srcChain string, destChain string) IBCPacket

func (IBCPacket) ValidateBasic ¶

func (ibcp IBCPacket) ValidateBasic() sdk.Error

type IBCReceiveMsg ¶

type IBCReceiveMsg struct {
	IBCPacket
	Relayer  sdk.Address
	Sequence int64
}

IBCReceiveMsg defines the message that a relayer uses to post an IBCPacket to the destination chain.

func (IBCReceiveMsg) Get ¶

func (msg IBCReceiveMsg) Get(key interface{}) interface{}

func (IBCReceiveMsg) GetSignBytes ¶

func (msg IBCReceiveMsg) GetSignBytes() []byte

func (IBCReceiveMsg) GetSigners ¶

func (msg IBCReceiveMsg) GetSigners() []sdk.Address

x/bank/tx.go SendMsg.GetSigners()

func (IBCReceiveMsg) Type ¶

func (msg IBCReceiveMsg) Type() string

func (IBCReceiveMsg) ValidateBasic ¶

func (msg IBCReceiveMsg) ValidateBasic() sdk.Error

type IBCTransferMsg ¶

type IBCTransferMsg struct {
	IBCPacket
}

IBCTransferMsg defines how another module can send an IBCPacket.

func (IBCTransferMsg) Get ¶

func (msg IBCTransferMsg) Get(key interface{}) interface{}

func (IBCTransferMsg) GetSignBytes ¶

func (msg IBCTransferMsg) GetSignBytes() []byte

func (IBCTransferMsg) GetSigners ¶

func (msg IBCTransferMsg) GetSigners() []sdk.Address
