Tests fail on 1.27 since trim_start was in stable in 1.30. Do not know why the nightly failed. Nightly failed for some build error. No idea what. Looks like AppVeyor could not merge from forks other than master. Might be a config problem.

trim_start() wasn't added until v1.30.0; trim_left() is deprecated v1.33.0.

So, if this, or something similar is used, the minimum rust version would have to be pushed up to v1.30.

In my local 'dev' fork, to suppress spurious compilation warnings, I marked all the locations with #[allow(deprecated)] and a MAINT comment (see 9cc9cf7). I'm not sure if there's a better solution, so I didn't push it up as a PR. But, I think it's either that, or push the minimum version to v1.30.

[meltinglava]

Indeed it is needed to bump minimum to 1.30. think this should be merged when/if another PR / commit forces the bump to >=1.30.

Can you rebase? I am fine with updating the minimum version required. Probably we'd go to Rust 1.31 so we can use 2018 edition features.

hope i did this right.

So i do not know why appveyor failed. Sry for takeing so long to respond

[Arcterus]

It looks like Appveyor just messed up again... It's not your fault. Also don't worry about it, I took a long time to respond before as well.

[Arcterus]

It also looks like you merged instead of rebasing. If you don't know how to rebase, I think this page should help. If you're still unsure, let me know and I'll try to walk you through it.

[meltinglava]

think i the rebase is right now. Please tell if it is not. Exams got in the way for doing it earlyer

Thanks for the contribution!
The fix for this same issue was already included in a large lint and CICD fixup PR (#1449).
We'd be happy to see you back with new contributions in the future.
