Functions ¶
func NewMsgServerImpl ¶
NewMsgServerImpl returns an implementation of the MsgServer interface for the provided Keeper.
Types ¶
type Keeper ¶
type Keeper struct {
// contains filtered or unexported fields
}
Keeper maintains the link to data storage and exposes getter/setter methods for the various parts of the state machine
func NewKeeper ¶
func NewKeeper( cdc codec.Codec, storeKey, memKey storetypes.StoreKey, authorityKeeper types.AuthorityKeeper, ) Keeper
NewKeeper creates new instances of the lightclient Keeper
func (Keeper) AddBlockHeader ¶
func (k Keeper) AddBlockHeader( ctx sdk.Context, chainID int64, height int64, blockHash []byte, header proofs.HeaderData, parentHash []byte, )
AddBlockHeader adds a new block header to the store and updates the chain state
func (Keeper) BlockHeader ¶
func (k Keeper) BlockHeader(c context.Context, req *types.QueryGetBlockHeaderRequest) (*types.QueryBlockHeaderResponse, error)
BlockHeader queries block header by hash
func (Keeper) BlockHeaderAll ¶
func (k Keeper) BlockHeaderAll(c context.Context, req *types.QueryAllBlockHeaderRequest) (*types.QueryBlockHeaderAllResponse, error)

func (Keeper) CheckNewBlockHeader ¶
func (k Keeper) CheckNewBlockHeader( ctx sdk.Context, chainID int64, blockHash []byte, height int64, header proofs.HeaderData, ) ([]byte, error)
CheckNewBlockHeader checks if a new block header is valid and can be added to the store It checks that the parent block header exists and that the block height is valid It also checks that the block header does not already exist It returns an error if the block header is invalid Upon success, it returns the parent hash
func (Keeper) CheckVerificationFlagsEnabled ¶
