Functions

func ReadBlockFromSnapshot

func ReadBlockFromSnapshot(r io.Reader, executionReader ExecutionBlockReaderByNumber, cfg *clparams.BeaconChainConfig) (*cltypes.SignedBeaconBlock, error)

func ReadBlockHeaderFromSnapshotWithExecutionData

func ReadBlockHeaderFromSnapshotWithExecutionData(r io.Reader) (*cltypes.SignedBeaconBlockHeader, uint64, libcommon.Hash, error)

ReadBlockHeaderFromSnapshotWithExecutionData reads the beacon block header and the EL block number and block hash.

func ReadRawBlockFromSnapshot

func ReadRawBlockFromSnapshot(r io.Reader, out io.Writer, executionReader ExecutionBlockReaderByNumber, cfg *clparams.BeaconChainConfig) (clparams.StateVersion, error)

func WriteBlockForSnapshot

func WriteBlockForSnapshot(w io.Writer, block *cltypes.SignedBeaconBlock, reusable []byte) ([]byte, error)

WriteBlockForSnapshot writes a block to the given writer in the format expected by the snapshot. buf is just a reusable buffer. if it had to grow it will be returned back as grown.
