Does this have no_std support? #38

Closed drewstone closed 5 years ago

AaronKutch commented 5 years ago

I can't remember if the current master branch or my reorganization_rebase branch works with no_std. I know that disabling all the default features removes the need for std, but you will have to try out my branch and open issues as they come. I have been waiting on Robbepop reviewing and accepting my PRs to get rid of some technical debt. Robbepop is quite busy and has not been able to review my latest refactor for a few months now. I should note that apint version 0.2.0 was released over a year ago, and there has been a bunch of breaking changes since then.

When I get some free time later this week, I can enable and disable all the feature flags, and add an integration test to see if no_std works. However, too many commits are riding on my PR from the delays. Could someone other than Robbepop help review the "Refactor and update to edition 2018" PR, so I can move forward finally?

Actually, now I remember that I just need to add a no_std flag so that the crate uses core instead of std. Would you like me to do this to the reorganization_rebase branch? The only user-facing problems I can remember is that there are warnings that I need to fix in upcoming PRs, I have not yet differentiated the from_str_radix and friends functions, and the rand dependency is really old and messes with cargo doc. I would update dependencies, but again I don't want to add much more to the commit tower.

Thanks for the responses! It's not huge, I also don't have much bandwidth but am looking for number libraries with no_std support to maybe explore some cryptography in WASM. Will keep an eye on the work if I get a spare moment.

If I would write this library today I would design it as no_std from on the beginning. Sadly this did not happen but I would really appreciate PRs for it. It is totally possible and should be done.

@drewstone optional no_std is going to be implemented by https://github.com/Robbepop/apint/pull/50. There is only one strange thing from blocking it.

Implemented. Closed.
