Please help me improve them, it doesn't feel complete yet. > I think it will also help people to upgrade if we add an example of how to get an actual `SessionState` reference from it (as a way to ease the migration) > > ```rust > let session_context = catalog_session. > .as_any() > .downcast_ref::<SessionState>() > .unwrap(); > ``` i like the idea. I added this as preformatted text, but it should be a code snippet that `cargo doc` can check for compilation. How should i handle this without introducing circular dependency between the new catalog module and the core? -- This is an automated message from the Apache Git Service.
