AFAIK both Rust and Elixir (a different story for next weeks) are not (yet) supported in SonarQube nor in SonarCloud, but it seems that we might get at least rust’s compiler and linter (clippy) output as an input for Sonar analysis.
If that’s actually possible, has one achieved it yet? If not, could anyone please point in the right direction for us to achieve such a goal?
Thanks Alexandre, it’s a good approach but needs both a parser from the output we have and a converter into the required format, which don’t seem to available at all, so I guess we might have to build it, but time is crucial these COVID-19 days (war-like scenario) I doubt if we could spare some time for such, unfortunately. 
If this is in the context of COVID-19, things are differents, I may help on that field.
Can you share a link to the format generated by clippy and an example of an actual output so I can play with it?
Alexandre, I meant how COVID has changed our company, our performance, and our projects. Unfortunately, this is not related to any studies regarding the virus or alike.
Nevertheless, I’m still sharing a sample Clippy output:

Finished dev [unoptimized + debuginfo] target(s) in 0.17sHello,
Your last message confirm what I found myself: rust-clippy only generates its results in the console and there is no option to ask rust-clippy to generate a JSON file.
I won’t personally engage myself into a project to parse the raw output of rust-clippy that may change without notice but the best would be to ask the guys of rust-clippy to support output formats such:
Alex
@Alexandre_Gigleux, could the JSON format, that @PaberGraham talk about, help to integrate Clippy lints in SonarCloud? I’m interested on it also.
Hello,
I’ve got a doubt it will be possible to integrate Clippy data into SonarCloud today, mainly because SonarCloud doesn’t know the language Rust at all, so I don’t know how it would look like (no syntax highlighting for example). All in all, I believe we should work together to collect your needs as Rust developers and at some point move forward and really support the language in SonarCloud. For that, don’t hesitate to express your needs such as rules (bugs? code smells? security?), coverage tool, IDE you would expect us to support as entries in https://community.sonarsource.com/c/suggestions/12
Alex
