Golang DataWriter.WriteUint32 Examples

Example #1

File: txin.go Project: spearson78/guardian

func (this *TxIn) WriteTo(w io.Writer) (int64, error) {
	var dw dataio.DataWriter
	dw.Init(w)

	err := dw.Write(this.Previous.Hash[:])
	if err != nil {
		return dw.Count(), err
	}

	err = dw.WriteUint32(this.Previous.Index)
	if err != nil {
		return dw.Count(), err
	}

	err = dw.WriteVarBytes(this.Script)

	}

	err = dw.WriteUint32(this.Sequence)
	if err != nil {
		return dw.Count(), err
