Encoding rules

[ghost]

Is there any description on the encoding rules? To put more clearly, why do -1 corresponds to xabi, hayu to 2592, and so on?

Also, I see that you made this library to study Rust. Good luck on your journey learning Rust!

Oh, I missed this one. The encoding rule is simple. As you can see, we have constants here:

• NEGATIVE_SYLLABLE: syllable to represent a negative number.
• SYLLABLES: an array of syllables, corresponding to each number.

Every negative number will be encoded into a word that starts with xa, then the rest will be treated as a positive number.
The positive number itself will be encoded using division and modulo operation. I'll use 2592 as an example:

• Modulo of 2592 by 100 (length of SYLLABLES array) is 92. If we use this as an index for looking up a value in SYLLABLES array, we'll found yu syllable.
• The number is divided by 100, resulting in 25, which will be processed again.
• Modulo of 25 by 100 is 25, which is ha on SYLLABLES array.
• Conclusion: the number is encoded as hayu.

If the number is negative, it'll be xahayu. Simple, huh?

Anyway, thanks for that! It's one in my learning-list that I hadn't ever learned until now, I forced myself by writing this crate. 😅

I see, interesting. Did you make the rule yourself, or are you inspired by something?

Cool, working on a project is definitely one of the better ways to learn a language!

No, it's based on munemo Ruby gem which is stated here and as you can see, munemo Ruby gem itself is also based on mnemo library, which is written on C.
