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...

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.

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.
