We have maturin packaged at 1.1.0 and I believe it is even used to build
a couple of packages.  python-rpds-py, which just landed in the repo
today, is probably the best short example of how to use a combination of
cargo and any other build system to build a project that doesn't really
need any phases overridden, just added/replaced.

Is there a specific version of pydantic that you need? I might be able
to put together something either using the crates in the master branch
or a newer version on the rust-team branch.
