Key Binary Document

Key Binary Document, also as KeyBinDoc, is an easy and flexible binary internet-transferable format, when binary data more than string data instead of JSON.

KeyBinDoc is hashmap-like, nullable and JavaScript-compatible, and these basic types are supported below:

1. NUL(0) - as null, property name is specified but no value is setted.
2. NUMBER(1) - as unknown typed number stored as ascii, f64 is the first selection and i64 as the second.
3. FALSE(2) and TRUE(3) - as both bool type.
4. BUFFER(4) - as &[u8].
5. STRING(5) - as UTF-8 String.
6. ARRAY(6) - as dynamic typed Array of KeyBinDoc items.
7. OBJECT(7) - as dynamic key-value Map of KeyBinDoc items.
