andygrove opened a new pull request, #2177:
URL: https://github.com/apache/datafusion-sqlparser-rs/pull/2177
## Summary
Refactors the parser to use `to_ident(&self)` instead of
`clone().into_ident(self)` when converting borrowed `Word` references to
`Ident`.
**Changes:**
- Replace 10 instances of `w.clone().into_ident(span)` with
`w.to_ident(span)`
- Remove misleading deprecation from `to_ident()` method
- Add documentation explaining when to use each method:
- `to_ident(&self)`: when you need to keep the original `Word`
- `into_ident(self)`: when you can consume the `Word`
- Add benchmarks comparing both approaches
## Rationale
The `to_ident()` method was deprecated with a note to use `into_ident()`
instead. However, when you only have a `&Word` reference, using `into_ident()`
requires cloning first: `w.clone().into_ident(span)`.
Benchmarks show both approaches have **equivalent performance** since the
String clone dominates in both cases:
```
word_to_ident/clone_into_ident_100x time: [1.49 µs 1.50 µs 1.50 µs]
word_to_ident/to_ident_100x time: [1.62 µs 1.63 µs 1.64 µs]
```
The change improves code clarity by using a single method call that directly
expresses intent.
## Test plan
- [x] All existing tests pass
- [x] `cargo clippy` passes
- [x] Added benchmarks to validate performance equivalence
