If a struct does not provide a public field that might be set by cleanenv, then the struct was ignored. This did make it impossible to implement a custom struct with SetValue. The change checks if a field implements SetValue. If SetValue is implemented we stop recursing into the type to looks for other fields that might be populated via cleanenv.

I also needed this functionality. My goals was to support validation of custom types during config loading. Before finding this PR, my forked version implements the solution the same way. @ilyakaznacheev first off, thank you for creating this library! It's been very helpful. Secondly, are there any blockers I could help with to get this merged? |

The new example test used to fail because SetValue was not called.
