Inline Word::to_ident

[fyrsta7]

Summary

This marks Word::to_ident as inline.

Word::to_ident is a small helper used while building identifier-heavy AST nodes. It clones the word value, copies the quote style and attaches the caller-provided span. Letting the compiler inline it removes the call boundary from parser hot paths without changing behavior.

Validation

• cargo fmt --all --check
• git diff --check
• cargo test
• cargo bench --manifest-path sqlparser_bench/Cargo.toml --bench sqlparser_bench -- --baseline upstream-main

Benchmark

I ran the repository benchmark suite on the same machine, first saving an upstream-main baseline from the current main branch and then comparing this branch against it.

Benchmark	Criterion change estimate
word_to_ident/to_ident_100x	14.44% faster
parse_identifiers/select_100_columns	2.58% faster
parse_identifiers/select_100_qualified_columns	2.56% faster
parse_compound_keyword_chain/chain_5	2.78% faster
parse_prefix_keyword_call_chain/chain_10	3.11% faster

The broader parsing benchmarks were also neutral to positive in this run, with the largest median regression at 1.51%.
