Why three different CI systems configured?

[michalfita]

I wanted to add building examples in CI, but they I've figured there are three different CI systems configured in this repository:

1. .github/workflows/rust.yml
2. .travis.yml
3. appveyor.yml

May I know why? And if not all are in use, why not remove redundant ones?

Hi, and thanks for the question!

These mostly come from historical reason. Travis was used first, before github actions was a thing (or at least before I learned about it). Appveyor was added next to test windows, as travis didn't easily support it. Github actions has since replaced both.

What about removing deprecated ones then?

Yup, appveyor has been removed for a while, and I just removed the travis file now after reading your post. Thanks for noticing!

Great, thanks!
