i ran through the rust “getting started” page (https://www.rust-lang.org/learn/get-started). it's a hello-world project that has the rust crab mascot say hello, and consists of 10 lines of code actually written.
it results in pulling in 25 separate dependencies totalling up to 97 megabytes.
for reference the entire cowsay source is 168 lines/4 kilobytes of perl.
@cstanhope But that's for all perl stuff on your system, cowsay itself uses precisely zero (0) external dependencies, only perl core modules that are always bundled with every perl install. These rust deps are all required by the hello-world program specifically, and even worse they're all indirect dependencies that I didn't even explicitly add.
@nytpu True, it's not an apples to apples comparison. I didn't try to exclude perl packages I never explicitly installed. So, does the resulting executable need all 97MB? Or is that just from all the build cruft?
(And I don't mean to bother you. I've been meaning to go and learn some Rust, so maybe I should go do that now and not pester somebody on the internet.)
@nytpu Oh geez. I didn't see the date of the post I was replying to. Sorry to jump on an old post. Thanks for the additional info. I'm digging in now for myself. It looks like the resulting release binary is around 413kB, with dynamic dependencies of libs: gcc, pthread, dl, c, and ld-linux-x86-64.
The debug build is about 1MB.
Thanks for the kind response and link, and thanks for the prompt to finally tentatively start exploring rust. :)
