I'm asking what this has to do with Linux. This is not a discussion of rust vs .NET. this is a discussion of Linux vs windows. So I don't see how your comment is at all relevant. If you compile the exact same rust code in the post on a windows machine, using cargo like in the post, then is the resulting windows executable file size really any different compared to the linux one?
