Types

type IBCPacket

type IBCPacket struct {
	SrcAddr   sdk.AccAddress `json:"src_addr"`
	DestAddr  sdk.AccAddress `json:"dest_addr"`
	Coins     sdk.Coins      `json:"coins"`
	SrcChain  string         `json:"src_chain"`
	DestChain string         `json:"dest_chain"`
}

nolint - TODO rename to Packet as IBCPacket stutters (golint) IBCPacket defines a piece of data that can be send between two separate blockchains.

func NewIBCPacket

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

func (IBCPacket) GetSignBytes added in v0.19.0

func (p IBCPacket) GetSignBytes() []byte

nolint

func (IBCPacket) ValidateBasic

func (p IBCPacket) ValidateBasic() sdk.Error

validator the ibc packey

type IBCReceiveMsg

type IBCReceiveMsg struct {
	IBCPacket
	Relayer  sdk.AccAddress
	Sequence uint64
}

nolint - TODO rename to ReceiveMsg as folks will reference with ibc.ReceiveMsg IBCReceiveMsg defines the message that a relayer uses to post an IBCPacket to the destination chain.

func (IBCReceiveMsg) GetSignBytes

func (msg IBCReceiveMsg) GetSignBytes() []byte

get the sign bytes for ibc receive message

func (IBCReceiveMsg) GetSigners

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

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

func (IBCReceiveMsg) Route added in v0.25.0

func (msg IBCReceiveMsg) Route() string

nolint

func (IBCReceiveMsg) Type

func (msg IBCReceiveMsg) Type() string

func (IBCReceiveMsg) ValidateBasic

func (msg IBCReceiveMsg) ValidateBasic() sdk.Error

type IBCTransferMsg

type IBCTransferMsg struct {
	IBCPacket
}

nolint - TODO rename to TransferMsg as folks will reference with ibc.TransferMsg IBCTransferMsg defines how another module can send an IBCPacket.

func (IBCTransferMsg) GetSignBytes

func (msg IBCTransferMsg) GetSignBytes() []byte

get the sign bytes for ibc transfer message

func (IBCTransferMsg) GetSigners

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

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

func (IBCTransferMsg) Route added in v0.25.0

nolint

func (IBCTransferMsg) Type

func (msg IBCTransferMsg) Type() string

func (IBCTransferMsg) ValidateBasic

func (msg IBCTransferMsg) ValidateBasic() sdk.Error

validate ibc transfer message

type Mapper added in v0.16.0

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

IBC Mapper

func NewMapper added in v0.16.0

func NewMapper(cdc *codec.Codec, key sdk.StoreKey, codespace sdk.CodespaceType) Mapper

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

func (Mapper) GetIngressSequence added in v0.16.0

func (ibcm Mapper) GetIngressSequence(ctx sdk.Context, srcChain string) uint64

TODO add description

func (Mapper) PostIBCPacket added in v0.16.0

func (ibcm Mapper) 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 (Mapper) ReceiveIBCPacket added in v0.16.0

func (ibcm Mapper) 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 (Mapper) SetIngressSequence added in v0.16.0

func (ibcm Mapper) SetIngressSequence(ctx sdk.Context, srcChain string, sequence uint64)

TODO add description
