Looks fine, but should rather go to somewhere in test/

I was wondering about that. Right now test is strictly C/C++. Once we have Go bindings, would tests of it go there too? Is it feasible with Go? Would any of this conflict with the cmake/gtest stuff?

Unittest should be placed by the given language convention. But this is rather integration test, so I'd rather put in test/rust_compilation or bindings/rust/test/.

Apparently can't move to test/rust-compilation, because it expects test to be a cargo directory for some reason:

$ cargo build
error: failed to read `/Users/alex/Projects/fizzy/test/Cargo.toml`

Caused by:
  No such file or directory (os error 2)

So binndings/rust/test if that works, otherwise it can stay as it is.

Replaced by #591. The branch name had a typo here.
