I shaved off 10 MiB from my binary in 2 hours!
I made a program using Macroquad, then I built it in release mode, the binary was 63 MiB in size.
So I used cargo vendor to have a better look at Macroquad and one of its dependencies, glam.
I then started to delete code, like, lots and lots of code(about 30_000 lines of code); none of it affected my main project, some of it became ‘dead_code’ just by removing the pub keyword.
The result is that my project was unaffected and the binary went down to 52 MiB.
Is there a way to automate removal of unneeded elements from dependencies? This is potentially huge.
Sure, but isn’t this in a dependency? Can’t be reached when only importing your crate anyways? And if you’re building a binary, I don’t think this could really considered exported, is what I mean :)
Yes that’s exactly what I want. The compiler should stop considering it accessible.
