rustdoc: catch and don't blow up on impl Trait cycles An odd feature of Rust is that `Foo` is invalid, but `Bar` is okay: type Foo<'a, 'b> = Box<dyn PartialEq<Foo<'a, 'b>>>; type Bar<'a, 'b> = impl PartialEq<Bar<'a, 'b>>; To get it right, track every time rustdoc descends into a type alias, so if it shows up twice, it can be write the path instead of infinitely expanding it. 2023-04-20 20:08:06 -05:00			`\|`
