error[E0038]: the trait `Foo` cannot be made into an object
--> $DIR/object-safety.rs:10:12
|
LL | let x: &dyn Foo = todo!();
| ^^^^^^^^ `Foo` cannot be made into an object
|
note: for a trait to be "object safe" 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>
--> $DIR/object-safety.rs:6:14

LL | trait Foo {
| --- this trait cannot be made into an object...
LL | async fn foo(&self);
| ^^^ ...because method `foo` is `async`
= help: consider moving `foo` to another trait
error: aborting due to previous error
