📝 Walkthrough

Walkthrough

The Rust manifest updates substrait-prost, substrait-extensions, and substrait-antlr from version 0.87.0 to 0.103.1. The substrait-prost build dependency is updated as well.

Changes

Rust dependency updates

Layer / File(s)	Summary
Update Substrait dependency versions rs/Cargo.toml	Runtime dependencies substrait-prost, substrait-extensions, and substrait-antlr now use version 0.103.1. The build dependency substrait-prost also uses version 0.103.1; its listed features are unchanged.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~5 minutes

Change: Other

Suggested reviewers: nielspardon

Merge Risk: 🟠 High · up to 452e8

The Rust build is blocked by parser code that still uses a removed Substrait field. Update those parsers or retain a compatible dependency version before merging.

In `@rs/Cargo.toml`:
- Line 38: The substrait-prost version no longer generates the legacy args
field; remove legacy-argument parsing and handle_legacy_arguments calls from the
scalar, window, and aggregate parsers, or pin substrait-prost to a version that
still generates args.

Remove the legacy argument handling

-    #[allow(deprecated)]
-    let legacy_arguments = proto_repeated_field!(x, y, args, parse_legacy_function_argument)
-        .1
-        .into_iter()
-        .map(|x| x.unwrap_or_default())
-        .collect();
     let arguments = proto_repeated_field!(x, y, arguments, parse_function_argument)
         .1
         .into_iter()
         .map(|x| x.unwrap_or_default())
         .collect();
...
-    let arguments = handle_legacy_arguments(y, arguments, legacy_arguments);

Apply this removal in the scalar, window, and aggregate parsers, or pin a dependency version that still generates args.

The enum-path statement is unrelated. rs/src/parse/expressions/mod.rs already uses substrait::expression::RexType::Enum.

In `@rs/Cargo.toml` at line 38, The substrait-prost version no longer generates
the legacy args field; remove legacy-argument parsing and
handle_legacy_arguments calls from the scalar, window, and aggregate parsers, or
pin substrait-prost to a version that still generates args.
