error[E0038]: the trait alias `EqAlias` is not dyn compatible
--> $DIR/object-fail.rs:7:17
|
LL | let _: &dyn EqAlias = &123;
| ^^^^^^^ `EqAlias` is not dyn compatible
|
note: for a trait to be dyn compatible it needs to allow building a vtable
for more information, visit <https://doc.rust-lang.org/reference/items/traits.html#dyn-compatibility>
--> $SRC_DIR/core/src/cmp.rs:LL:COL
|
= note: ...because it uses `Self` as a type parameter
|
::: $DIR/object-fail.rs:3:7
|
LL | trait EqAlias = Eq;
| ------- this trait is not dyn compatible...
error[E0191]: the value of the associated type `Item` in `Iterator` must be specified
--> $DIR/object-fail.rs:9:17

LL | let _: &dyn IteratorAlias = &vec![123].into_iter();
| ^^^^^^^^^^^^^ help: specify the associated type: `IteratorAlias<Item = Type>`
