Support for rust programming language

[WaDelma]

Support for rust could be added.

I actually like this proposal. I feel like this could make to a really nice project - do you feel like starting to work on adding support for this language?

[WaDelma]

Yeah I would like to start working on it. Not sure how fast it's going progress due other courses. Also this should be probaply split into multiple tasks.

Awesome!
I see a few things we need to figure out on the rust side, and a bunch of tasks for the tmc-langs.
I have added some of the tasks here.
Let's plan this a bit more before creating a bunch of issues and a milestone for this.

Rust:

• Figure out a way to nicely implement the available points, test method relation; like the @Points annotation in java.
• Maybe a niceish lib for making testing nicer e.g. read/write stdin - maybe reflection like "hey, do you have method X, ok cool you do. let's call it with these params"

In Java it takes in a string of different point names, where each point is separated by white space. e.g @Points("124.1 124.2 124.3 124.4 test-point")
And in C we have tmc_register_test(s, test_sum, "1 test-point")

I see at least following sub tasks:

• New maven module (I wouldn't include it to the tmc-langs-util just yet, but we can include it to the main pom.xml..) ((other products depend on the tmc-langs-util to include all langs modules))
• Compiling code from langs
• Running tests from langs
• Parsing test results from langs
• Generating the STUB, MODEL SOLUTIONS etc. (we have another issue refactoring this atm.)
• Having figuring out available points

@nygrenh @Mession you were creating the C and python support for langs. Did I overlook some tasks; do you have anything to add?

Aside from implementing all the methods specified in LanguagePlugin (most likely by extending AbstractLanguagePlugin), the plugin also has to implement a StudentFilePolicy.
