var SentinelProof = []byte{0x01}

SentinelProof defines the 09-localhost sentinel proof. Submission of nil or empty proofs is disallowed in core IBC messaging. This serves as a placeholder value for relayers to leverage as the proof field in various message types. Localhost client state verification will fail if the sentintel proof value is not provided.

Functions

func NewClientState 

func NewClientState(height clienttypes.Height) exported.ClientState

NewClientState creates a new 09-localhost ClientState instance.

func RegisterInterfaces 

func RegisterInterfaces(registry codectypes.InterfaceRegistry)

RegisterInterfaces registers the tendermint concrete client-related implementations and interfaces.

Types

type ClientState 

type ClientState struct {
	// the latest block height
	LatestHeight types.Height `protobuf:"bytes,1,opt,name=latest_height,json=latestHeight,proto3" json:"latest_height"`
}

ClientState defines the 09-localhost client state

func (ClientState) CheckForMisbehaviour 

func (ClientState) CheckForMisbehaviour(_ sdk.Context, _ codec.BinaryCodec, _ storetypes.KVStore, _ exported.ClientMessage) bool

CheckForMisbehaviour is unsupported by the 09-localhost client type and performs a no-op, returning false.

func (ClientState) CheckSubstituteAndUpdateState 

func (ClientState) CheckSubstituteAndUpdateState(_ sdk.Context, _ codec.BinaryCodec, _, _ storetypes.KVStore, _ exported.ClientState) error

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

func (ClientState) ClientType 

func (ClientState) ClientType() string

ClientType returns the 09-localhost client type.

func (*ClientState) Descriptor 

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

func (ClientState) ExportMetadata 

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

ExportMetadata is a no-op for the 09-localhost client.

func (ClientState) GetLatestHeight 

func (cs ClientState) GetLatestHeight() exported.Height

GetLatestHeight returns the 09-localhost client state latest height.

func (ClientState) GetTimestampAtHeight 

func (ClientState) GetTimestampAtHeight(ctx sdk.Context, _ storetypes.KVStore, _ codec.BinaryCodec, _ exported.Height) (uint64, error)

GetTimestampAtHeight returns the current block time retrieved from the application context. The localhost client does not store consensus states and thus cannot provide a timestamp for the provided height.

func (ClientState) Initialize 

func (ClientState) Initialize(ctx sdk.Context, cdc codec.BinaryCodec, clientStore storetypes.KVStore, consState exported.ConsensusState) error

Initialize ensures that initial consensus state for localhost is nil.

func (*ClientState) Marshal 

func (m *ClientState) Marshal() (dAtA []byte, err error)

func (*ClientState) MarshalTo 

func (m *ClientState) MarshalTo(dAtA []byte) (int, error)

func (*ClientState) MarshalToSizedBuffer 

func (m *ClientState) MarshalToSizedBuffer(dAtA []byte) (int, error)

func (*ClientState) ProtoMessage 

func (*ClientState) ProtoMessage()

func (*ClientState) Reset 

func (m *ClientState) Reset()

func (*ClientState) Size 

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

func (ClientState) Status 

func (ClientState) Status(_ sdk.Context, _ storetypes.KVStore, _ codec.BinaryCodec) exported.Status

Status always returns Active. The 09-localhost status cannot be changed.

func (*ClientState) String 

func (m *ClientState) String() string

func (*ClientState) Unmarshal 

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

func (ClientState) UpdateState 

func (cs ClientState) UpdateState(ctx sdk.Context, cdc codec.BinaryCodec, clientStore storetypes.KVStore, _ exported.ClientMessage) []exported.Height

UpdateState updates and stores as necessary any associated information for an IBC client, such as the ClientState and corresponding ConsensusState. Upon successful update, a list of consensus heights is returned. It assumes the ClientMessage has already been verified.

func (ClientState) UpdateStateOnMisbehaviour 

func (ClientState) UpdateStateOnMisbehaviour(_ sdk.Context, _ codec.BinaryCodec, _ storetypes.KVStore, _ exported.ClientMessage)

UpdateStateOnMisbehaviour is unsupported by the 09-localhost client type and performs a no-op.

func (ClientState) Validate 

func (cs ClientState) Validate() error

Validate performs a basic validation of the client state fields.

func (ClientState) VerifyClientMessage 

func (ClientState) VerifyClientMessage(_ sdk.Context, _ codec.BinaryCodec, _ storetypes.KVStore, _ exported.ClientMessage) error

VerifyClientMessage is unsupported by the 09-localhost client type and returns an error.

func (ClientState) VerifyMembership 

func (ClientState) VerifyMembership(
	ctx sdk.Context,
	store storetypes.KVStore,
	_ codec.BinaryCodec,
	_ exported.Height,
	_ uint64,
	_ uint64,
	proof []byte,
	path exported.Path,
	value []byte,
) error

VerifyMembership is a generic proof verification method which verifies the existence of a given key and value within the IBC store. The caller is expected to construct the full CommitmentPath from a CommitmentPrefix and a standardized path (as defined in ICS 24). The caller must provide the full IBC store.

func (ClientState) VerifyNonMembership 

func (ClientState) VerifyNonMembership(
	ctx sdk.Context,
	store storetypes.KVStore,
	_ codec.BinaryCodec,
	_ exported.Height,
	_ uint64,
	_ uint64,
	proof []byte,
	path exported.Path,
) error

VerifyNonMembership is a generic proof verification method which verifies the absence of a given CommitmentPath within the IBC store. The caller is expected to construct the full CommitmentPath from a CommitmentPrefix and a standardized path (as defined in ICS 24). The caller must provide the full IBC store.

func (ClientState) VerifyUpgradeAndUpdateState 

func (ClientState) VerifyUpgradeAndUpdateState(
	_ sdk.Context,
	_ codec.BinaryCodec,
	_ storetypes.KVStore,
	_ exported.ClientState,
	_ exported.ConsensusState,
	_,
	_ []byte,
) error

VerifyUpgradeAndUpdateState returns an error since localhost cannot be upgraded

func (*ClientState) XXX_DiscardUnknown 

func (m *ClientState) XXX_DiscardUnknown()

func (*ClientState) XXX_Marshal 

func (m *ClientState) XXX_Marshal(b []byte, deterministic bool) ([]byte, error)

func (*ClientState) XXX_Merge 

func (m *ClientState) XXX_Merge(src proto.Message)

func (*ClientState) XXX_Size 

func (m *ClientState) XXX_Size() int

func (*ClientState) XXX_Unmarshal 

func (m *ClientState) XXX_Unmarshal(b []byte) error

func (ClientState) ZeroCustomFields 

func (cs ClientState) ZeroCustomFields() exported.ClientState

ZeroCustomFields returns the same client state since there are no custom fields in the 09-localhost client state.
