refactor: simplify few string related interactions Few small optimizations: check_doc_keyword: don't alloc string for emptiness check check_doc_alias_value: get argument as Symbol to prevent needless string convertions check_doc_attrs: don't alloc vec, iterate over slice. replace as_str() check with symbol check get_single_str_from_tts: don't prealloc string trivial string to str replace LifetimeScopeForPath::NonElided use Vec<Symbol> instead of Vec<String> AssertModuleSource use FxHashSet<Symbol> instead of BTreeSet<String> CrateInfo.crate_name replace FxHashMap<CrateNum, String> with FxHashMap<CrateNum, Symbol> |
