peterxcli opened a new pull request, #25178:
URL: https://github.com/apache/datafusion/pull/25178

   ## Which issue does this PR close?
   
   Closes #24618.
   
   ## Rationale for this change
   
   This change makes the compiler catch fields that serialization does not 
handle. When a field is added to a dynamic filter, scalar subquery expression, 
or its protobuf payload, the corresponding hook must account for it. This helps 
prevent new fields from being silently dropped when expressions are encoded and 
decoded.
   
   ## What changes are included in this PR?
   
   All four encoding and decoding hooks for `DynamicFilterPhysicalExpr` and 
`ScalarSubqueryExpr` explicitly list every field without a rest pattern. 
Dynamic filter encoding also destructures the snapshot of its shared inner 
state, and decoding handles the expression ID carried by the enclosing message.
   
   Comments explain why caches, watch channels, cached type and nullability 
checks, and subquery results are omitted, including how they are rebuilt or 
supplied.
   
   The PR also replaces one use of unstable `std::assert_matches` in an 
existing execution test with `assert!(…is_ok())`, allowing the required checks 
to run on the pinned stable compiler.
   
   ## What is the testing strategy for this PR?
   
   Existing tests cover filter identity, shared updates, remapped children, 
subquery metadata, nested result scopes, and execution after serialization. The 
physical expression suite passed 1,739 tests with 2 ignored, and all 13 
relevant protobuf integration tests passed.
   
   The full extended workspace run passed 11,591 Rust tests, with 8 ignored, 
and completed all 516 SQLLogicTest files. Formatting, Clippy with all targets 
and features and warnings denied, and the complete `./dev/rust_lint.sh` suite 
also passed.
   
   ## Are there any user-facing changes?
   
   No.
