'Simplest way to replace deprecated std::error::Error::description
warning: use of deprecated associated function `std::error::Error::description`: use the Display impl or to_string()
error::Error::description(self)
Does this justify the whole Display impl boilerplate or can I can away with the simpler to_string(). What was in description that's now deprecated (and I will miss dearly because of its simplicity)?
Solution 1:[1]
Add the Display implementation; that's how errors are done, now.
You can minimize boilerplate by using the thiserror derive macro library to generate one for you, using strings you annotate your error type with.
