Nor does the Rust compiler.

Rust's build system, Cargo, does however. And many C build systems do as well, e.g. https://cmake.org/cmake/help/latest/guide/using-dependencies...

Optionally. Cargo doesn’t have to connect to the internet, and even has command line switches to fail if it tries to.

Good to know.

Thank you for the tip. I shall do

ifconfig eth0 down

before compiling to avoid such issues.
