--> $DIR/async-recursive-generic.rs:8:5

LL | async fn foo_recursive(&self, n: usize) -> T {
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
...
LL | self.foo_recursive(n - 1).await
| ------------------------------- recursive call here

= note: a recursive `async fn` call must introduce indirection such as `Box::pin` to avoid an infinitely sized future
error: aborting due to 1 previous error
