hey, newbie question here — I’m looking at the rust engine and trying to run the tests from the master branch, and running into some test failures. Don’t know if it’s a “my environment” thing or a known issue or what, but this is what is happening:

> /build-support/bin/native/cargo test --manifest-path src/rust/engine/Cargo.toml --all
...
<lots of tests pass>
...
   Doc-tests bazel_protos

running 7 tests

failures:

error: aborting due to previous error

Couldn't compile the test.

Anything to worry about, or any known workaround?

--tests

is the flag you want to cargo - we have auto-generated code which has invalid doc comments which rust thinks are doc tests, and that flag is the way to say don't try to run them
