Rust is a systems programming language that runs blazingly fast, prevents segfaults, and guarantees thread safety. https://www.rust-lang.org This will build rust from source, which requires using the "official" stage0 compiler for the version being built from rust-lang.org. Currently, "official" means the previous stable version. If you already have rust and cargo installed, this slackbuild will use these to bootstrap itself. You can also force either behaviour through the LOCAL_BOOTSTRAP=yes|no parameter. LOCAL_BOOTSTRAP=no ./rust.SlackBuild
