Types

type Keeper 

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

func NewKeeper 

func NewKeeper(cdc codec.BinaryMarshaler, key store.StoreKey, ck types.ClientKeeper) Keeper

func (Keeper) ClientConnections 

func (q Keeper) ClientConnections(c context.Context, req *types.QueryClientConnectionsRequest) (*types.QueryClientConnectionsResponse, error)

ClientConnections implements the Query/ClientConnections gRPC method

func (Keeper) ConnOpenAck 

func (k Keeper) ConnOpenAck(
	ctx sdk.Context,
	connectionID string,
	clientState exported.ClientState,
	version *types.Version,
	counterpartyConnectionID string,
	proofTry []byte,
	proofClient []byte,
	proofConsensus []byte,
	proofHeight exported.Height,
	consensusHeight exported.Height,
) error

ConnOpenAck relays acceptance of a connection open attempt from chain B back to chain A (this code is executed on chain A).

NOTE: Identifiers are checked on msg validation.

func (Keeper) ConnOpenConfirm 

func (k Keeper) ConnOpenConfirm(
	ctx sdk.Context,
	connectionID string,
	proofAck []byte,
	proofHeight exported.Height,
) error

ConnOpenConfirm confirms opening of a connection on chain A to chain B, after which the connection is open on both chains (this code is executed on chain B).

NOTE: Identifiers are checked on msg validation.

func (Keeper) ConnOpenInit 

func (k Keeper) ConnOpenInit(
	ctx sdk.Context,
	clientID string,
	counterparty types.Counterparty,
	version *types.Version,
	delayPeriod uint64,
) (string, error)

ConnOpenInit initialises a connection attempt on chain A. The generated connection identifier is returned.

NOTE: Msg validation verifies the supplied identifiers and ensures that the counterparty connection identifier is empty.

func (Keeper) ConnOpenTry 

func (k Keeper) ConnOpenTry(
	ctx sdk.Context,
	previousConnectionID string,
	counterparty types.Counterparty,
	delayPeriod uint64,

	counterpartyVersions []exported.Version,
	proofInit []byte,
	proofClient []byte,
	proofConsensus []byte,
	proofHeight exported.Height,
	consensusHeight exported.Height,
) (string, error)

ConnOpenTry relays notice of a connection attempt on chain A to chain B (this code is executed on chain B).

NOTE:

  • Here chain A acts as the counterparty
  • Identifiers are checked on msg validation

func (Keeper) GetConnection 

func (k Keeper) GetConnection(ctx sdk.Context, connectionID string) (types.ConnectionEnd, bool)

func (Keeper) GetNextConnectionSequence 

func (k Keeper) GetNextConnectionSequence(ctx sdk.Context) uint64

GetNextConnectionSequence gets the next connection sequence from the store.

func (Keeper) GetTimestampAtHeight
