Thank God this VMM is written in Rust, otherwise I would be very skeptical. I don't care about features or purpose or technical advantages, give me Rust or give me death.
For real, I find it so odd to tack on "written in Rust" to every new project that's announced that uses Rust. (As someone who uses Rust in their day job)
I sort of see "written in Rust" as a feature. I guess they could say "memory safe implementation" but I suspect they'd also say "written in Ada" if it was in fact written in Ada as an example of another safe language.
