how to divorce two impl?

Help! I want to divorce ReadFn from ListFN - bypassing the Queries mutual closure behavior so I can better isolate some logic. My need is to get an independent ListFn...

 undefined

    
fn queries_&lt;'a>() -> Queries&lt;
  impl ReadFn&lt;'a, PostView, (PostId, Option, bool)>,
  impl ListFn&lt;'a, PostView, PostQuery&lt;'a>>,
> {

Context: https://github.com/LemmyNet/lemmy/blob/main/crates/db_views/src/post_view.rs

For sake of clarity... I'm not wanting to break the whole Queries joined closure marriage project-wide, just this one source file I want to be able to copy/paste this code twice and have just a single closure for ListFn.

Thank you.

Unfortunately your code here in this post is unreadable with the buggy html escaping in it. Consider posting to the official rust playground and creating a shared link. And/or report a bug to lemmy about the broken quoting.

  I have, weeks ago.

  I did share a link to GitHub, is that not good enough or something? Here is a screen shot for you.
  
  Oh, this seems to be specific to the SQL framework you use after looking into it. I thought it was a general rust question about function parameters, sorry. Unfortunately I'm not familiar with that sql framework (or any other, I'm an embedded developer, not a web dev).
  Hope you find someone who knows diesel, and sorry again I couldn't help you.
