| error[E0391]: cycle detected when expanding type alias `Bar` |
| --> $DIR/issue-110629-private-type-cycle-dyn.rs:1:38 |
| | |
| LL | type Bar<'a, 'b> = Box<dyn PartialEq<Bar<'a, 'b>>>; |
| | ^^^^^^^^^^^ |
| | |
| = note: ...which immediately requires expanding type alias `Bar` again |
| = note: type aliases cannot be recursive |
| = help: consider using a struct, enum, or union instead to break the cycle |
| = help: see <https://doc.rust-lang.org/reference/types.html#recursive-types> for more information |
| note: cycle used when collecting item types in top-level module |
