'Fill match arms' should work with existing match arms
Addresses #3039 This essentially adds missing match arms. The algorithm for this can get complicated rather quickly so bail in certain conditions and rely on a PlaceholderPat. The algorighm works as such: - Iterate through the Enum Def Variants - Attempt to see if the variant already exists as a match arm - If yes, skip the enum variant. If no, include it. - If it becomes complicated, rather than exhaustively deal with every branch, mark it as a "partial match" and simply include the placeholder. Conditions for "complication": - The match arm contains a match guard - Any kind of nested destrucuring Order the resulting merged match branches as such: 1. Provided match arms 2. Missing enum variant branch arms 3. End with Placeholder if required - Add extra tests
