type Blockstore

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

StoreBlock writes the block number to disk.

func (*Blockstore) StoreSignature

func (b *Blockstore) StoreSignature(sig string) error

StoreBlock writes the signature to disk.

func (*Blockstore) TryLoadLatestBlock

func (b *Blockstore) TryLoadLatestBlock() (*big.Int, error)

TryLoadLatestBlock will attempt to load the latest block for the chain/relayer pair, returning 0 if not found. Passing an empty string for path will cause it to use the home directory.

func (*Blockstore) TryLoadLatestSignature

func (b *Blockstore) TryLoadLatestSignature() (string, error)

TryLoadLatestBlock will attempt to load the latest block for the chain/relayer pair, returning 0 if not found. Passing an empty string for path will cause it to use the home directory.
