Add Rust branch

[ochibani]

This is a rust code that is still being tested.
The goal is to follow the same approach that the Python code was written in order to have working rust code, and then to improve it.
I think the code can be improved in the future, like using libbtrfsutil, dropping python-anytree, and using the command line less.
The benefit from this is having a single executable binary file that can be easily packaged.

Thanks for the PR. I will do it. In fact, I was about to announce this. Removing anytree and making ash more solid, cross-platform has been high on my priority list for the project.

Good progress!
I'll leave this PR open till it's in good shape and the three mentioned issues are resolved.

@ochibani There would be some updates in the next few days.
I would say, keep a close eye on the python code changes and reflect them on Rust as they come. Thanks!

Also, I'd recommend joining private #dev channel on Discord. We also have Matrix.

If you look at the new code submissions recently, you might realize I'm slowly relaxing the strict POSIX requirement and implementing functions etc. pythonically. (again python might not be target language and it's just what's used right now) I highly recommend following the same thing as much as you can so merge could be easy in future. As much as you can avoid shell.

Good work!

For now, I am unable to catch up with changes, but don't worry, I will add them to the code.

[ochibani]

I'll begin working on the cli, while also investigating and updating the code.

Assuming this is meant for Arch Linux, is there a way to avoid mentioning it here (to make this file more generic)?

[ochibani]

Just default value for compiler. It can be changed from cargo during build time, but I think I may change this.

[ochibani]

I will begin adding auto-completion support for bash, fish, and zsh.

[ochibani]

Add support for apt and dnf should be the last task here.
