Valid question, but no. Borgo takes inspiration from Rust but is still a vastly different language. Even though it has algebraic data types its type system is not Rust's. Another big difference is that it sticks with Go's interfaces instead of traits.

I think Borgo sits at an interesting place in the design space. I just believe there are vast plains of unsettled land in the strongly typed GC-less direction and a language that really addressed all complaints about Go would have live there.
