Add lint 'ref_option_ref' #1377 This lint checks for usage of `&Option<&T>` which can be simplified as `Option<&T>` as suggested in #1377. This WIP PR is here to get feedback on the lint as there's more cases to be handled: * statics/consts, * associated types, * type alias, * function/method parameter/return, * ADT definitions (struct/tuple struct fields, enum variants) changelog: Add 'ref_option_ref' lint |
