I started something. How do you like Rust? > I've never written anything in Rust. I am not opposed to the language, since I don't know much about it (although I've heart praise for Rust from some people), but am not much enthuiastic about this program in particular to be written in it. For embedded systems, for example, gcc was for a long time the only needed compiler. Now embedded system often need at least Python/Lua/Perl. If I wanted to embed this ledtool and it is written in Rust, I will need one more compiler and its environment. So if you insist on Rust for ledtool, I will most probably pass, but I am still interested in working on the kernel part of the LED subsystem.
