type Header struct {
	blockif.Header
}

Header represents a block header in the Harmony blockchain.

func (*Header) DecodeRLP

EncodeRLP encodes the header using tagged RLP representation.

func (*Header) Hash 

func (h *Header) Hash() ethcommon.Hash

Hash returns the block hash of the header. This uses HeaderRegistry to choose and return the right tagged RLP form of the header.

func (*Header) IsLastBlockInEpoch added in v1.10.0 

func (h *Header) IsLastBlockInEpoch() bool

IsLastBlockInEpoch returns True if it is the last block of the epoch. Note that the last block contains the shard state of the next epoch.

func (*Header) Logger 

func (h *Header) Logger(logger *zerolog.Logger) *zerolog.Logger

func (Header) String added in v1.3.3 

func (h Header) String() string

String ..

func (*Header) With 

func (h *Header) With() HeaderFieldSetter

With returns a field setter context for the header.

Call a chain of setters on the returned field setter, followed by a call of Header method. Example: 

header := NewHeader(epoch).With().
	ParentHash(parent.Hash()).
	ShardID(parent.ShardID()).
	Number(new(big.Int).Add(parent.Number(), big.NewInt(1)).
	Header()
