Interesting that this is in a self-developed subset/dialect of Rust called Crust which attempts to treat it as a better C, using unsafe everywhere among other things.
A pretty recent work: https://github.com/sergev/BCause .
Nice, but it really needs to be written in B and self-hosted.
Always nice to see more B. Here's mine: https://github.com/aap/b
Had a go at this a while back: https://github.com/elvircrn/bcomp.
Hate to see Tsoding was using Rust for this. Rust is as far removed from recreational programming than any other language.
This is the most tsoding thing possible.
Fun to see that it implements codegen for Uxn :)
