Have you ever tried to compile a helloworld Rust program in --release mode? If yes, have you seen its binary size? Suffice to say, it’s not exactly small. Or at least it wasn’t small until recently. This post details how I found about the issue and my attempt to fix it in Cargo.

    So this is around 4MB less, right? The small app I'm currently working on is 15MB so with this change it will be 11MB. Nice but nothing revolutionary. It will have bigger impact on a really tiny apps. I guess that's why it wasn't resolved for so long.

      It's also what I understood from what I read but I assume it was just a poor choice of word. Debug symbols are way too important for debugging to be stripped by default.

        In fact, this new default will be used for any profile which does not enable debuginfo anywhere in its dependency chain, not just for the release profile.

        On reflection I imagine the debug profile does enable this

        I guess it may use external debug symbols and strip them from the binary by default.

        Otherwise seems like a massive change haha
