What do you mean? Cargo downloads packages from the internet by default programs do exactly what they’re programmed to do. No more and no less.

Just because you’re targeting windows xp doesn’t mean you need to run windows xp to do development.

With cargo --offline, Rust has better than average support for offline build.

What insistence? I do 99% of my Rust development with this ~/.cargo/config.toml:

  [net]
  offline = true
  
  [source]
  
  [source.crates-io]
  replace-with = "debian"
  
  [source.debian]
  directory = "/usr/share/cargo/registry"

Works great.
