# Building a rust project may require setting up toolchains. Rustup cannot handle parallel requests, hence it may fail to
# finish the setup if multiple projects want to install a same version. To mitigate the situation, we force cargo targets
# to be invoked sequentially by adding linear dependency relations between them.
# Another way to do so is to use JOB_POOL with single concurrency. However, it is Ninja specific and it seems to have bugs
# with a large number of threads.
