pub fn call_with_item<U, E>( &self, f: impl FnOnce(Option<T>) -> Result<(T, U), E>, ) -> Result<U, E>
Run call a closure after obtaining a slot, potentially with a pre-built item.
The calling thread will block until there is an available slot. Once there is, the provided closure will be called, potentially with an item returned from a previously called closure. Upon completion, if the closure returns a new item, the item will be provided to a subsequent closure.
