Description

Whenever the order of a struct or enum would be completely irrelevant, I like to keep them in alphabetic order. However, this gets slightly annoying to maintain when adding new fields. Therefore I propose an optional automatic sorting attribute, think #[rustfmt::sort].

My first idea was to create a clippy lint for this, but having this done automatically would be the best.

Research direction

The issue names no files, tests, or entry points. Start by locating rustfmt's handling of attributes and ordering for structs and enums; done would mean an optional sorting attribute works for cases where declaration order is irrelevant, with behavior and scope clarified.
