[Rust] String-vs-str concept exercise

[gilescope]

Creating well escaped csv files is something every developer should strive for so I think this is a helpful exercise! Also demostrates consumption of an owned value. (Fixes #1095 )

It's says: "Forgot to run Prettier?" - is there a tool I should be running to check the .md files conform?

For security reasons, /format does not trigger CI builds when the PR has been submitted from a fork. To make the required checks pass, you need to trigger a build through one of the following ways:

• Push an empty commit to this branch: git commit --allow-empty -m "Trigger builds".
• Close and reopen the PR.
• Push a regular commit to this branch.

Thanks for contributing @gilescope! I love the CSV idea. That is something I have to work with frequently so find this a grand combination of Rust and a practical problem.

Pro tip: you can run the formatting script locally if you want with EXERCISM_PRETTIER_VERSION=2.1.2 ./bin/format.sh. It runs it on everything in the repository.

Ok updated version.

There's no slicing done at all. I think that's fine and lives in a more &str focused exercise. - maybe something parsing related? (A get out of this without allocating exercise... -- hmm makes me wonder if we can have some exercises that are no_std so that we can teach &str without there being the possibiliity of allocating... yes there's some fun potentially to be had there.)

Cool - I am sure more things will come to me once I see it in situ on the site. I'm sure we will revisit as I know more about the process.
