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