Functions

func RegisterInterfaces 

func RegisterInterfaces(registry codectypes.InterfaceRegistry)

RegisterInterfaces register the ibc interfaces submodule implementations to protobuf Any.

Types

type ClientState 

type ClientState struct {
	// self chain ID
	ChainId string `protobuf:"bytes,1,opt,name=chain_id,json=chainId,proto3" json:"chain_id,omitempty" yaml:"chain_id"`
	// self latest block height
	Height types.Height `protobuf:"bytes,2,opt,name=height,proto3" json:"height"`
}

ClientState defines a loopback (localhost) client. It requires (read-only) access to keys outside the client prefix.

func NewClientState 

func NewClientState(chainID string, height clienttypes.Height) *ClientState

NewClientState creates a new ClientState instance

func (*ClientState) CheckHeaderAndUpdateState 

func (cs *ClientState) CheckHeaderAndUpdateState(
	ctx sdk.Context, _ codec.BinaryMarshaler, _ sdk.KVStore, _ exported.Header,
) (exported.ClientState, exported.ConsensusState, error)

CheckHeaderAndUpdateState updates the localhost client. It only needs access to the context

func (ClientState) CheckMisbehaviourAndUpdateState 

func (cs ClientState) CheckMisbehaviourAndUpdateState(
	_ sdk.Context, _ codec.BinaryMarshaler, _ sdk.KVStore, _ exported.Misbehaviour,
) (exported.ClientState, error)

CheckMisbehaviourAndUpdateState implements ClientState Since localhost is the client of the running chain, misbehaviour cannot be submitted to it Thus, CheckMisbehaviourAndUpdateState returns an error for localhost

func (ClientState) CheckProposedHeaderAndUpdateState 

func (cs ClientState) CheckProposedHeaderAndUpdateState(
	ctx sdk.Context, _ codec.BinaryMarshaler, _ sdk.KVStore, _ exported.Header,
) (exported.ClientState, exported.ConsensusState, error)

CheckProposedHeaderAndUpdateState returns an error. The localhost cannot be modified by proposals.

func (ClientState) ClientType 

func (cs ClientState) ClientType() string

ClientType is localhost.

func (*ClientState) Descriptor 

func (*ClientState) Descriptor() ([]byte, []int)

func (ClientState) ExportMetadata 

func (cs ClientState) ExportMetadata(_ sdk.KVStore) []exported.GenesisMetadata

func (ClientState) GetChainID 

func (cs ClientState) GetChainID() string

GetChainID returns an empty string

func (ClientState) GetFrozenHeight 

func (cs ClientState) GetFrozenHeight() exported.Height

GetFrozenHeight returns an uninitialized IBC Height.

func (ClientState) GetLatestHeight 

func (cs ClientState) GetLatestHeight() exported.Height

GetLatestHeight returns the latest height stored.

func (ClientState) GetProofSpecs 

func (cs ClientState) GetProofSpecs() []*ics23.ProofSpec

GetProofSpecs returns nil since localhost does not have to verify proofs

func (ClientState) Initialize 

func (cs ClientState) Initialize(_ sdk.Context, _ codec.BinaryMarshaler, _ sdk.KVStore, consState exported.ConsensusState) error

Initialize ensures that initial consensus state for localhost is nil

func (ClientState) IsFrozen 

func (cs ClientState) IsFrozen() bool

IsFrozen returns false.

func (*ClientState) ProtoMessage 

func (*ClientState) ProtoMessage()

func (*ClientState) Reset 

func (m *ClientState) Reset()

func (*ClientState) Size 

func (m *ClientState) Size() (n int)

func (*ClientState) String 

func (m *ClientState) String() string

func (*ClientState) Unmarshal 

func (m *ClientState) Unmarshal(dAtA []byte) error

func (ClientState) Validate 

func (cs ClientState) Validate() error

Validate performs a basic validation of the client state fields.

func (ClientState) VerifyChannelState 

func (cs ClientState) VerifyChannelState(
	store sdk.KVStore,
	cdc codec.BinaryMarshaler,
	_ exported.Height,
	prefix exported.Prefix,
	_ []byte,
	portID,
	channelID string,
	channel exported.ChannelI,
) error

VerifyChannelState verifies a proof of the channel state of the specified channel end, under the specified port, stored on the local machine.

func (ClientState) VerifyClientConsensusState 

func (cs ClientState) VerifyClientConsensusState(
	sdk.KVStore, codec.BinaryMarshaler,
	exported.Height, string, exported.Height, exported.Prefix,
	[]byte, exported.ConsensusState,
) error

VerifyClientConsensusState returns nil since a local host client does not store consensus states.

func (ClientState) VerifyClientState 

func (cs ClientState) VerifyClientState(
	store sdk.KVStore, cdc codec.BinaryMarshaler,
	_ exported.Height, _ exported.Prefix, _ string, _ []byte, clientState exported.ClientState,
