feat: generate names for tuple-struct in add-missing-match-arms fix #18034. This PR includes the following enhancement: - Introduced a `NameGenerator` in `suggest_name`, which implements an automatic renaming algorithm to avoid name conflicts. Here are a few examples: ```rust let mut generator = NameGenerator::new(); assert_eq!(generator.suggest_name("a"), "a"); assert_eq!(generator.suggest_name("a"), "a1"); assert_eq!(generator.suggest_name("a"), "a2"); assert_eq!(generator.suggest_name("b"), "b"); assert_eq!(generator.suggest_name("b"), "b1"); assert_eq!(generator.suggest_name("b2"), "b2"); assert_eq!(generator.suggest_name("b"), "b3"); assert_eq!(generator.suggest_name("b"), "b4"); assert_eq!(generator.suggest_name("b3"), "b5"); ``` - Updated existing testcases in ide-assists for the new `NameGenerator` (only modified generated names). - Generate names for tuple structs instead of using wildcard patterns in `add-missing-match-arms`. |
