Is there a reason you are tying to build it as a dylib? https://github.com/GuillaumeGomez/minifier-rs/blob/81851f08301dd149c2de25889ade81291ca6de74/Cargo.toml#L23

Old (and bad apparently) habit. Good catch, thanks a lot!

Fixed the initial issue, now just need to make the minification process work as expected. :)

Could we minimize these two *.js files at build.rs of rustdoc?

I'd rather prefer that we don't. We could but then disabling minification would be a bit more complicated and I'm not sure it's worth it.

Use include_str! instead of include_bytes! for the static files to avoid this UTF-8 check.

Seems good to me. What do you think, @ollie27?

Yeah this looks good.

For the std docs it might make more sense for the minification to be done by rustbuild so it can apply to the docs generated by mdBook as well but this seems like a reasonable start anyway.

For now it's experimental. If we have no issue for a given time, we might want to expand this to other tools as well. Thanks for your review!
