Types

type BlockStore

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

func NewBlockStore

func NewBlockStore(db KeyValueReaderWriter) *BlockStore

func (*BlockStore) GetLastStoredBlock

func (bs *BlockStore) GetLastStoredBlock(domainID uint8) (*big.Int, error)

GetLastStoredBlock queries the blockstore and returns latest known block

func (*BlockStore) GetStartBlock

func (bs *BlockStore) GetStartBlock(domainID uint8, startBlock *big.Int, latest bool, fresh bool) (*big.Int, error)

GetStartBlock queries the blockstore for the latest known block. If the latest block is greater than configured startBlock, then startBlock is replaced with the block right after the latest known block.

func (*BlockStore) StoreBlock

func (bs *BlockStore) StoreBlock(block *big.Int, domainID uint8) error

StoreBlock stores block number per domainID into blockstore

type KeyValueReader

type KeyValueReader interface {
	GetByKey(key []byte) ([]byte, error)
}

type KeyValueReaderWriter

type KeyValueReaderWriter interface {
	KeyValueReader
	KeyValueWriter
}

type KeyValueWriter

type KeyValueWriter interface {
	SetByKey(key []byte, value []byte) error
}

type NonceStore

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

func NewNonceStore

func NewNonceStore(db KeyValueReaderWriter) *NonceStore

func (*NonceStore) GetNonce

func (ns *NonceStore) GetNonce(chainID *big.Int) (*big.Int, error)

GetNonce queries the blockstore and returns latest nonce

func (*NonceStore) StoreNonce

func (ns *NonceStore) StoreNonce(chainID *big.Int, nonce *big.Int) error

StoreNonce stores nonce per chainID
