Code Review

correctness: 0/4edge case handling: 1/4introduced bug risk: 1/4maintainability idioms: 1/4

The agent patch likely does not satisfy the intended change: it appears to introduce a compile-breaking test error, does not clearly wire the new span trait into public AST surfaces, and relies heavily on empty-span fallbacks that limit usable source-location tracking.

4 findings

Duplicate struct field assignment in tests causes compile failure

major

The same `Ident` literal assigns `span` twice, which Rust rejects (`field specified more than once`), so the patch likely fails to compile.

tests/sqlparser_bigquery.rs:680

New span trait/module appears unhooked from AST module surface

major

A new `src/ast/spans.rs` is added, but the shown `src/ast/mod.rs` change only adds imports and does not show `mod spans`/re-export wiring, so `Spanned` may not be reachable as intended.

src/ast/spans.rs:34

Broad fallback-to-empty spans undermines source location recovery

major

Multiple key match arms return `Span::empty()` (including wildcard catch-alls), which means many valid AST nodes produce missing locations instead of actionable spans.

src/ast/spans.rs:497

Legacy token path injects empty spans by construction

minor

The parser path that wraps plain tokens now assigns `Span::empty()` for every token, which can propagate empty locations unless all call paths use richer tokenization.

src/parser/mod.rs:372
