You're missing how rust works. The function is explicitly allowed to fail, which is why it returns a Result<(), Error>. They're using the function calls within for their side effects. The ? at the end of each line signals that the function will short-circuit return with an error if the function call fails, and only if it is successful it returns the actual value: they just don't care about this value, hence the let _ =. Basically, they are doing the equivalent of:

  let _, err = function_call();
  if err {
    return err
  }

Something to note here is that most (if not all) of the "medical data" acquired by Axis experiments is useless: a lot of it is on the order of "if we make someone really cold they die". The methodology was, unsurprisingly, generally biased, non-reproducible, and often cruel for the sake of it, rather than unethical out of necessity.

IMO there's a nice parallel between useless evidence from bad experiments, and useless business practices from unethical companies. If you want to take the lessons but leave the bad stuff, often you'll find there's nothing left.
