sourcefn reduce<OP, ID>(self, identity: ID, op: OP) -> Self::Item where

fn reduce<OP, ID>(self, identity: ID, op: OP) -> Self::Item where
OP: Fn(Self::Item, Self::Item) -> Self::Item + Sync + Send,
ID: Fn() -> Self::Item + Sync + Send,
Reduces the items in the iterator into one item using op.
The argument identity should be a closure that can produce
“identity” value which may be inserted into the sequence as
needed to create opportunities for parallel execution. So, for
example, if you are doing a summation, then identity() ought
to produce something that represents the zero for your type
(but consider just calling sum() in that case). Read more

OP: Fn(Self::Item, Self::Item) -> Self::Item + Sync + Send,

sourcefn fold<T, ID, F>(self, identity: ID, fold_op: F) -> Fold<Self, ID, F> where

F: Fn(T, Self::Item) -> T + Sync + Send,
ID: Fn() -> T + Sync + Send,
T: Send,
Parallel fold is similar to sequential fold except that the
sequence of items may be subdivided before it is
folded. Consider a list of numbers like 22 3 77 89 46. If
you used sequential fold to add them (fold(0, |a,b| a+b),
you would wind up first adding 0 + 22, then 22 + 3, then 25 +
77, and so forth. The parallel fold works similarly except
that it first breaks up your list into sublists, and hence
instead of yielding up a single sum at the end, it yields up
multiple sums. The number of results is nondeterministic, as
is the point where the breaks occur. Read more
