error[E0599]: the method `countx` exists for struct `Filter<Map<Repeat, fn(&u64) -> &u64 {identity::<u64>}>, {closure@hrtb-doesnt-borrow-self-2.rs:111:30}>`, but its trait bounds were not satisfied

LL | pub struct Filter<S, F> {
| ----------------------- method `countx` not found for this struct because it doesn't satisfy `_: StreamExt`

note: `StreamExt` defines an item `countx`, perhaps you need to implement it
