Functions ¶

func CreateBackup ¶

func CreateBackup(
	conn *grpc.ClientConn,
	logger hclog.Logger,
	from uint64,
	to *uint64,
	outPath string,
	overwriteFile bool,
	enableZstdCompression bool,
	zstdLevel int,
) (resFrom uint64, resTo uint64, err error)

CreateBackup fetches blockchain data with the specific range via gRPC and save this data as binary archive to given path

func RestoreChain ¶

func RestoreChain(log hclog.Logger, chain blockchainInterface, filePath string) error

RestoreChain reads blocks from the archive and write to the chain

Types ¶

type Metadata ¶

type Metadata struct {
	Latest     uint64
	LatestHash types.Hash
}

Metadata is the data stored in the beginning of backup

func (*Metadata) MarshalRLP ¶

func (m *Metadata) MarshalRLP() []byte

MarshalRLP returns RLP encoded bytes

func (*Metadata) MarshalRLPTo ¶

func (m *Metadata) MarshalRLPTo(dst []byte) []byte

MarshalRLPTo sets RLP encoded bytes to given byte slice

func (*Metadata) MarshalRLPWith ¶

func (m *Metadata) MarshalRLPWith(arena *fastrlp.Arena) *fastrlp.Value

MarshalRLPWith appends own field into arena for encode

func (*Metadata) UnmarshalRLP ¶

func (m *Metadata) UnmarshalRLP(input []byte) error

UnmarshalRLP unmarshals and sets the fields from RLP encoded bytes

func (*Metadata) UnmarshalRLPFrom ¶

func (m *Metadata) UnmarshalRLPFrom(p *fastrlp.Parser, v *fastrlp.Value) error

UnmarshalRLPFrom sets the fields from parsed RLP encoded value
