Writing my first library/cli in Rust. Never felt so productive in a systems level language but I still quite haven't internalized the variable ownership system and will probably look back at my code in a few months with total disgust. I'm on Rust's discord server (https://discord.gg/rust-lang) if any fellow learners want to chat.
I too started picking up Rust with the goal of trying out embedded development. I'm taking it slow though -- working through the book and a little cli tool. I am also on the discord.
