See <https://sqlite.org/testing.html#statement_versus_branch_cove...>. Does Rustrover produce branch coverage reports?

Yes! A quick google brings up cargo-llvm-cov[1], which is a rust wrapper around llvm source code coverage. It has an unstable --branch command for branch coverage, but branch coverage currently has some language level limitations[2].
