Struct BasicHeader

pub struct BasicHeader { /* private fields */ }

Indicates the chunk stream and message header’s format. This header has 3 types.

Total Length	Message Header Format	Chunk ID	Chunk ID Range
8	2	6	0 - 63
16	2	8	64 - 319
24	2	16	64 - 65599

Unit of every item is bits. Basic header which is and above 16 bits has a flag bits in first 8 bits. It means whether chunk ID is 16 bits. Note if chunk ID is 16 bits, encoding/decoding it as Little Endian is required.

Any Chunk ID which is and above 64 is required to add/subtract 64 from it when reading/writing. This means to compensate a 6 bits which were replaced with the flag.
