Cannot find derive macro `Model` in this scope

Hey @adamfriedland no problem. You will notice here (https://github.com/thedodd/wither/blob/master/wither/examples/readme.rs) that the example code actually uses the following import: use wither::{prelude::*, Result};, so in your code sample above, I would recommend that you replace your use wither::Model; with user wither::prelude::*;.

What is happening here is that you are actually importing the wither::Model trait, not the derive macro. They are both named the same, however the prelude module exposes them both.

The other option, depending on your preference, would be to modify your derive to be #[derive(Debug, wither::Model, ...)] because Rust will know that you are referring to the derive-macro in that case.

Cheers

Yes, I took at look at the references and saw what you meant. There appears to be reference ambiguity that the compiler doesn't know how to resolve correctly. Prior to this, I did end up just opting into the alpha build and that actually resolved quite a few of the issues I had, even if it sacrifices indexing in the interim. Keep up the good work @thedodd. We need a good strongly typed mongodb implementation.

@adamfriedland awesome! Glad to hear it. Thanks for the encouragement :). Definitely a lot going on, but hopefully we'll be able to get the index PR landed soon so we can cut the official 0.9 release.
