[feature] lower-case option?

[dvdplm]

It would be nice to have the option to use lower-case letters when converting to string. In my case I use this to generate string keys for redis values and my aim is to be compatible with a previous javascript codebase. In Javascript Number(123456789).toString(36) outputs 21i3v9 while Radix gives 21I3V9.

Thanks!

EDIT: fwiw, the BigNum crates to_str_radix(36) also uses lower-case.

You can achieve this effect by converting the str e.g. RadixNum::from(42 as u8).as_str().to_lowercase(). Does that work for your use case?

.to_lowercase()

Absolutely, and that's what I do. It is not in a performance sensitive part of the code. It was more of a suggestion for other scenarios where the extra allocation might be a problem.

What you suggest can definitely be done, in principle, and if I had infinite resources I would definitely simply implement it.
However, my resources are limited (mostly time is relevant here), and I also have no concrete use case for the feature; and given that .to_lowercase() is fast enough for your use case, I'd say that at least at this moment, neither do you.

If there is at least 1 active user that actually needs the extra efficiency, it can easily be a worthwhile feature to implement, but as it currently stands it looks like a bunch of effort (+ future maintenance costs) for not a lot of concrete gain, at least from my perspective.
