What would make a standalone Rust executable 20 MB in size? Last time I checked, Rust did not expect to carry libc with it, and can run entirely without a runtime.
For purposes of comparison, the Rust compiler (which is the most extensive Rust program on my computer at the moment) clocks in at 8MB.
EDIT: Servo, which is the largest Rust program in existence at the moment, is 21MB. Personally I doubt the above claim that writing this in C would reduce the binary size by 95%. I obviously don't have any statically-linked written-in-C web browsers on hand, but if I poke around in Chrome's install directory I see 85MB of DLLs (the entire directory is about 475MB, though surely not all of that is due to binaries).
I am Updated my comment (GP) to indicate I was talking entirely about compiler size, not executable product size.
Is the 8MB rust compiler statically or dynamically linked to LLVM? It's been a few years, but I never got a statically linked LLVM-using program below 30MB (unstripped, I think stripped was 16MB but I don't remember)
