The "link" is just the repos rather than asking AI to hallucinate an answer. Rust's repo contains 2.2M LOC. The dotnet runtime contains 1.5M lines of C++.

Now if we remove in tree tests from the totals, we arrive at 1.5M lines of C++ (most tests are written in C# as you would expect) and 1.7M lines of Rust.

However, this does not exclude safe Rust code. I don't have a tool off hand that can provide a precise count of lines of unsafe code but we can get some general estimates. There are 1958 instances of "unsafe fn" out of 103,205 instances of "fn ". Further there are 11,545 instances of "unsafe " in the Rust repo while there are 10,768 instances of "unsafe " in the runtime repo.

Given that unsafe functions comprise less than 2% of all functions in the Rust repo, I think my claims are reasonable.
