Derive Macro rustler_codegen::NifException

#[derive(NifException)]
{
    // Attributes available to this derive:
    #[module]
    #[rustler]
}

Implementation of the NifException macro that lets the user annotate a struct that will be translated directly from an Elixir exception to a Rust struct. For example, the following struct, annotated as such:

#[derive(Debug, NifException)]
#[module = "AddException"]
pub struct AddException {
    message: String,
}

This would be translated by Rustler into:

defmodule AddException do
  defexception message: ""
end
