Can `ctor` be used to initialize doctests?

[ivan-aksamentov]

Thank you for the fantastic crate!

I succesfully use ctor in order to initialize my tests, notably I initialize color_eyre, which makes output much prettier:

#[cfg(test)]
mod tests {
  use crate::utils::global_init::global_init;
  use ctor::ctor;

  #[ctor]
  fn init() {
    global_init();
  }
}

However, it does not work for doctests. I tried various permutations of things, none worked - the function is not called. Some of my attempts on Ubuntu 22.04:

#[cfg(doctest)]
mod tests {
  use crate::utils::global_init::global_init;
  use ctor::ctor;

  #[ctor]
  fn init() {
    global_init();
  }
}

#[cfg(any(test, doctest))]
mod tests {
  use crate::utils::global_init::global_init;
  use ctor::ctor;

  #[ctor]
  fn init() {
    global_init();
  }
}

#[cfg(doctest)]
#[ctor::ctor]
fn init() {
  utils::global_init::global_init();
}

Have anyone managed to run ctor with for doctests? Please share your experience.

Or is this something that ctor does not support, perhaps due to technical limitations?

Note that the doctests appear to be working inside the library -- it could be due to something like #306.

This should be fixed as part of #334 - I'm no longer using a sub-module which should allow this to work.
