value borrowed here after move

[blissful lantern]

You could probably just give a borrowed path to fs::copy

std::fs::copy(&path, &home_dir).unwrap();

Consider doing download().unwrap() in your main, otherwise you're ignoring potential errors (the compiler should warn you about it)

Though you don't seem to ever return an error out of that function so that probably won't change much

Try debugging some things, notably your paths

Do you get no output at all ?

Are you running it in debug mode ?

[blazing temple]

Command::new(&home_dir)
    .output()
``` captures the output and doesn't print it

does the program do something other than print something?
