error[E0038]: the trait `Eq` cannot be made into an object
--> $DIR/object-fail.rs:7:13
|
LL | let _: &dyn EqAlias = &123;
| ^^^^^^^^^^^ `Eq` cannot be made into an object
|
note: for a trait to be "dyn-compatible" it needs to allow building a vtable to allow the call to be resolvable dynamically; for more information visit <https://doc.rust-lang.org/reference/items/traits.html#object-safety>
--> $SRC_DIR/core/src/cmp.rs:LL:COL
|
= note: the trait cannot be made into an object because it uses `Self` as a type parameter
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>`
