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 added in v0.1.4 

func NewClientState(height clienttypes.Height) exported.ClientState

NewClientState creates a new 09-localhost ClientState instance.

func RegisterInterfaces added in v0.1.4 

func RegisterInterfaces(registry codectypes.InterfaceRegistry)

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

Types

type ClientState added in v0.1.4 

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 added in v0.1.4 

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

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

func (ClientState) CheckSubstituteAndUpdateState added in v0.1.4 

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

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

func (ClientState) ClientType added in v0.1.4 

func (cs ClientState) ClientType() string

ClientType returns the 09-localhost client type.

func (*ClientState) Descriptor added in v0.1.4 

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

func (ClientState) ExportMetadata added in v0.1.4 

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

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

func (ClientState) GetLatestHeight added in v0.1.4 

func (cs ClientState) GetLatestHeight() exported.Height

GetLatestHeight returns the 09-localhost client state latest height.

func (ClientState) GetTimestampAtHeight added in v0.1.4 

func (cs ClientState) GetTimestampAtHeight(ctx sdk.Context, _ sdk.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 added in v0.1.4 

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

Initialize ensures that initial consensus state for localhost is nil.

func (*ClientState) Marshal added in v0.1.4 

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

func (*ClientState) MarshalTo added in v0.1.4 

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

func (*ClientState) MarshalToSizedBuffer added in v0.1.4 

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

func (*ClientState) ProtoMessage added in v0.1.4 

func (*ClientState) ProtoMessage()

func (*ClientState) Reset added in v0.1.4 

func (m *ClientState) Reset()

func (*ClientState) Size added in v0.1.4 

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

func (ClientState) Status added in v0.1.4 

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

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

func (*ClientState) String added in v0.1.4 

func (m *ClientState) String() string

func (*ClientState) Unmarshal added in v0.1.4 

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

func (ClientState) UpdateState added in v0.1.4 

func (cs ClientState) UpdateState(ctx sdk.Context, cdc codec.BinaryCodec, clientStore sdk.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 added in v0.1.4 

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

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

func (ClientState) Validate added in v0.1.4 

func (cs ClientState) Validate() error

Validate performs a basic validation of the client state fields.

func (ClientState) VerifyClientMessage added in v0.1.4 

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

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

func (ClientState) VerifyMembership added in v0.1.4 

func (cs ClientState) VerifyMembership(
	ctx sdk.Context,
	store sdk.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 added in v0.1.4 

func (cs ClientState) VerifyNonMembership(
	ctx sdk.Context,
	store sdk.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 added in v0.1.4 

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

VerifyUpgradeAndUpdateState returns an error since localhost cannot be upgraded

func (*ClientState) XXX_DiscardUnknown added in v0.1.4 

func (m *ClientState) XXX_DiscardUnknown()

func (*ClientState) XXX_Marshal added in v0.1.4 

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

func (*ClientState) XXX_Merge added in v0.1.4 

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

func (*ClientState) XXX_Size added in v0.1.4 

func (m *ClientState) XXX_Size() int

func (*ClientState) XXX_Unmarshal added in v0.1.4 

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

func (ClientState) ZeroCustomFields added in v0.1.4 

func (cs ClientState) ZeroCustomFields() exported.ClientState

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