Use `supported | experimental` features everywhere in tests.

This actually was a bit tricky to implement, because it broke the formatting -- I discovered we use rustfmt for formatting the `Debug` output, which, while it mkaes sense, seems probably unnecessary if we do some plumbing. But I couldn't figure out the plumbing right now, so I filed b/272530008 instead.

After reflecting for this bug for a bit, I decided the sensible thing is to try to share the logic for both in one helper function, even if it seems a little awkward to do so -- having _no_ shared functionality is essentially what caused it.

Crubit: C++/Rust Bidirectional Interop Tool

Build status

Extremely experimental interop tooling for C++ and Rust.

Please don‘t use, this is an experiment and we don’t yet know where will it take us. There will be breaking changes without warning. Unfortunately, we can't take contributions at this point.

Building Crubit

$ apt install clang lld bazel
$ git clone git@github.com:google/crubit.git
$ cd crubit
$ bazel build --linkopt=-fuse-ld=/usr/bin/ld.lld //rs_bindings_from_cc:rs_bindings_from_cc_impl

Using a prebuilt LLVM tree

$ git clone https://github.com/llvm/llvm-project
$ cd llvm-project
$ CC=clang CXX=clang++ cmake -S llvm -B build -DLLVM_ENABLE_PROJECTS='clang' -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=install
$ cmake --build build -j
$ # wait...
$ cmake --install build
$ cd ../crubit
$ LLVM_INSTALL_PATH=../llvm-project/install bazel build //rs_bindings_from_cc:rs_bindings_from_cc_impl
