Cargo - the Rust package manager - is included in this build.
This script may take a while to complete (just over an hour for x86_64, just
over 1.5 hours for x86 on a 10 core machine) and will require about 7 GB of
disk space for its temporary directory. It defaults to "/tmp/SBo" and you may
redefine it like this:
TMP=/your/temporary/dir ./rust.SlackBuild
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.
