Struct FoldChunks
#[must_use = "iterator adaptors are lazy and do nothing unless consumed"]
pub struct FoldChunks<I, ID, F> { /* private fields */ }FoldChunks is an iterator that groups elements of an underlying iterator and applies a
function over them, producing a single value for each group.
This struct is created by the fold_chunks() method on IndexedParallelIterator
