the coreutil rust flavor is 16MB per its release build. after strip it cuts down to 10MB, that's the smallest size you can have.<p>Comparing to c version coreutils, which totals up to 5.8MB, rust does have a slight size "problem", its size is 70% larger even with the busybox-all-in-one style.<p>you're actually forced to do it the busybox style, otherwise each single small utility of coreutils will be about similar size, say, 6MB for each one, then it will just blow up really fast.<p>I commented somewhere else, the rust stdlib by default(AND by design) is statically linked, which is totally different from the shared stdlibs like C and C++ etc, that will leads to large size when you have a few of rust release binaries. I have never figured out why Rust can not do the shared-stdlib -just-like-c-c++ yet.
