Golang Buffer.Len Examples

Example #1

File: adminBlock.go Project: FactomProject/factomd

// Write out the AdminBlock to binary.
func (b *AdminBlock) MarshalBinary() ([]byte, error) {
	// Marshal all the entries into their own thing (need the size)
	var buf2 primitives.Buffer
	for _, v := range b.ABEntries {
		data, err := v.MarshalBinary()
		if err != nil {
			return nil, err
		}
		buf2.Write(data)
	}

	b.Header.SetMessageCount(uint32(len(b.ABEntries)))
	b.Header.SetBodySize(uint32(buf2.Len()))

	data, err := b.Header.MarshalBinary()
	if err != nil {
		return nil, err
	}

	var buf primitives.Buffer
	buf.Write(data)

	// Write the Body out
	buf.Write(buf2.DeepCopyBytes())

	return buf.DeepCopyBytes(), err
