Trait Generator

pub trait Generator: Send + Sync {
    type Item;

    // Required method
    fn generate<'life0, 'life1, 'async_trait>(
        &'life0 self,
        input: &'life1 str,
    ) -> Pin<Box<dyn Future<Output = Vec<Self::Item>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait,
             'life1: 'async_trait;
}

Generator is a kind of Source but it takes input. It is not envisaged that Generator will return a large number of items.

Generator can be used to implement a calculator (that needs a user input).

Required Associated Types
