1165-1167: Improve error message formatting.The error message in
check_opaque_modifies_completenesscould be formatted for better readability. Consider using multi-line formatting for long strings.- &format!("function `{}` is opaque but its specification does not have a modifies clause for `{}`", - fun_env.get_full_name_str(), - env.display(mem)), + &format!( + "function `{}` is opaque but its specification does not have a modifies clause for `{}`", + fun_env.get_full_name_str(), + env.display(mem) + ),
