Which doesn't help me a bit. Every additional bit that the another
language creeps in drastically reduces the maintainability of the kernel
as an integrated project. The only reason Linux managed to survive so
long is by not having internal boundaries, and adding another language
complely breaks this. You might not like my answer, but I will do
everything I can do to stop this. This is NOT because I hate Rust.
While not my favourite language it's definitively one of the best new
ones and I encourage people to use it for new projects where it fits.
I do not want it anywhere near a huge C code base that I need to
maintain.
