The following suggestion is incorrect, as it doesn't account for the binding: ``` error[E0599]: no method named `poll` found for type parameter `F` in the current scope --> $DIR/pin-needed-to-poll-3.rs:19:28 | LL | impl<F> Future for FutureWrapper<F> | - method `poll` not found for this type parameter ... LL | let res = self.fut.poll(cx); | ^^^^ method not found in `F` | help: consider pinning the expression | LL ~ let res = let mut pinned = std::pin::pin!(self.fut); LL ~ pinned.as_mut().poll(cx); | ```
