I highly recommend the Rustlings project for practicing the basic concepts we learn in this class. These completely optional, not graded/submitted exercises can help you to teach Rust programming to your "fingers".
The recommended exercises for this week:
structsenumsoptionsstrings
This assignment contains a single Rust crate w.r.t structs and enums in Rust.
Your job is to make sure that crate compiles and builds properly and passes all of the built-in tests.
I placed // TODO comments in the code where I expect you to add implementation code. The test code is clearly marked with a // DO NOT EDIT BELOW THIS LINE comment. This should be evident: changing the test code is a (not too intelligent) way of cheating. I will handle any such attempts accordingly. However, you are allowed and encouraged to look at the test code to better understand what is expected from you.
You can always check your work with cargo test. You can also run individual tests by running cargo test <test-name> (see the names below).
The crate contains a dummy main() function. You can use this function for your own needs.It is up to you if and how you want to use this for your development work. You can use cargo run to see your the execution results of your main() function. The only important requirement is that this function should not break the compilation/build process.
Make sure you commit and push your assignment repository once you manage to run cargo test without any errors or warnings.
The homework is graded by test (no partial credits are given for failed tests):
| Test | Points |
|---|---|
| test_new | 10 |
| test_debug | 5 |
| test_eq | 5 |
| test_clone | 3 |
| test_copy | 3 |
| test_from_name | 15 |
| test_from_hex | 15 |
| test_to_hex | 5 |
| test_distance | 7 |
| test_closest_base_color | 15 |
| test_to_grayscale | 5 |
| test_darken | 7 |
| test_mix | 5 |
Once you push your solution to the repository, GitHub Classroom will run the automated test. I highly recommend to verify your results of this CI/CD worflow - I use these results for grading your work.
