 integrate Rust do tests (unit and integration)? assume we want to migrate
 gradually, but want to look at using all Rust eventually."

 > Currently tor has C unit and integration tests, and Rust unit tests. The
 problem we are currently facing is how to write Rust integration tests
 that call C- see #25386.
 >
 > From https://trac.torproject.org/projects/tor/ticket/25639#comment:9, it
 sounds like FireFox/Servo do not have Rust integration tests that call C
 dependencies, and instead only have Rust unit tests and C unit/integration
 tests.

 For clarification, we are creating a shared crate for linking per
 discussion above, hence why this particular issue can be closed.
