Zigbus is a D-Bus implemented in zig.
For specification, see https://dbus.freedesktop.org/doc/dbus-specification.html.
Zig version: 0.11.0-dev.3936+8ae92fd17
WIP: Type System, Serialization/Deserialization, Message Format
By alignment, D-Bus Wire Format specifies the start position of a data in a byte stream(or, a message).
For example, since INT16 has an alignment of 2, INT16 data must start at 2n.
Also, since INT64 has an alignment of 8, a data of the type must start at 8n.
Let's take an example.
If two numbers of INT16 and INT64 lie in a message, respectively, in little endian,
the message must be shaped as:
0x01 0x00 0x00 0x00 0x00 0x00 0x00 0x00
0x02 0x00 0x00 0x00 0x00 0x00 0x00 0x00
The first two bytes are the bytes of INT16 number, which represents 1.
And, the next six bytes are padding to meet the alignment of the next INT64 number.
Finally, the next 8 bytes are bytes of the INT64 number, which represents 2.
