  3. What is the difference with https://github.com/rust-lang/datafrog ? It’s a Datalog engine written by Frank McSherry on top of differential dataflow, that’s used here also

  4. …compilation semantics. There is a reason why rust has a datalog engine build into the compiler ( https://github.com/rust-lang/datafrog ). Which is imho totally rad and awesome, but really hard to fully form a mental model of without a spec.

  5. There's also a Datalog implementation at https://github.com/rust-lang/datafrog . The Polonius reimplementation of the Rust borrowchecker uses Datafrog: https://github.com/rust-lang/polonius/

  8. …defines the Rust borrow checker as Datalog rules, and went from differential dataflow to datafrog ( https://github.com/rust-lang/datafrog ). 4. If you want to check out other incremental Datalog environments, in addition to IncA, there are…
