func DecodeBlockTx(data []byte, typeFilter transactions.TxType) (transactions.ContractCall, uint32, error)

DecodeBlockTx tries to deserialize the type, index and decoded value of a tx.

func EncodeBlockTx(tx transactions.ContractCall, txIndex uint32) ([]byte, error)

EncodeBlockTx tries to serialize type, index and encoded value of transactions.ContractCall.

func ReadUint32(r io.Reader, v *uint32) error

ReadUint32 will read four bytes and convert them to a uint32 from the Tx byteOrder. The result is put into v.

func ReadUint64(r io.Reader, v *uint64) error

ReadUint64 will read four bytes and convert them to a uint64 from the Tx byteOrder. The result is put into v.

func Search(n uint64, f func(uint64) (bool, error)) (uint64, error)

Search replicate sort.Search() upon uint64 type with error return.

func WriteUint32(w io.Writer, value uint32) error

WriteUint32 Tx utility to use a Tx byteOrder on internal encoding.

func WriteUint64(w io.Writer, value uint64) error

WriteUint64 Tx utility to use a common byteOrder on internal encoding.
