It's designed to meet our embedding needs: in Firefox for desktops, Firefox for Android, Firefox for iOS, and Project Tofino (Node + Electron).

Widespread adoption a la SQLite is not one of our goals.

Rust meets our goals just fine… and it also produces demonstrably more correct software than C, which is important to us. (Not to mention leveraging the borrow checker and data race avoidance to provide safe near-automatic parallelization, which is a neat trick that's not in C's quiver.)

I would rather build Mentat in Swift or JavaScript than in C.
