I think this is pretty useful, but it might be worth mentioning serde-rs/serde#2178 as a limitation. |

This adds an example for a useful pattern where a type needs to be validated arbitrarily (via
TryFromon an inner type) during deserialization. This comes directly from serde-rs/serde#642 (comment) where I learned the pattern.I couldn't figure out on my own how to do this via browsing https://serde.rs, so I went to the issue tracker where I found this recipe, so it seems like a good candidate for the examples section.
