Required Methods

fn prepare_item<'life0, 'async_trait>( &'life0 self, input: In, ) -> Pin<Box<dyn Future<Output = Result<Self::Intermediate>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Action that does not have a special way of batching, and the caller can simply executed in parallel on many items at once.

fn process_batch<'life0, 'async_trait>( &'life0 self, mid: Vec<Self::Intermediate>, ) -> Pin<Box<dyn Future<Output = Result<Out>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Action that does have a special way of batching, and this particular type can define the batching approach.
