I installed Rust on an offline system via an offline installer. Howbeit, this offline installer does not include rustup and I only know how to cross-compile using rustup commands.
Moreover, I was wondering how to add a target and cross-compile without rustup, if it’s even possible. I can drop files to the offline system but the system cannot be online. If there’s an offline way of adding rustup, I would accept that as an answer as well. Thanks!
