class BatchedSemigroup[T] extends Semigroup[Batched[T]]

Compacting semigroup for batched values.

This semigroup ensures that the batch's tree structure has fewer than batchSize values in it. When more values are added, the tree is compacted using s.

    Returns an instance of T calculated by summing all instances in iter in one pass.

    Returns an instance of T calculated by summing all instances in iter in one pass. Returns None if iter is empty, else Some[ T].

    iter

    instances of T to be combined

    returns

    None if iter is empty, else an option value containing the summed T
