error[E0391]: cycle detected when expanding type alias `Bar`
|
|
--> $DIR/private-type-cycle-dyn-110629.rs:3:38

|
|
|
|
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
