Collects the results of the iterator into the specified vector. The vector is always truncated before execution begins. If possible, reusing the vector across calls can lead to better performance since it reuses the same backing buffer.

pub fn unzip_into_vecs<A, B>(
    self,
    left: &mut Vec<A, Global>,
    right: &mut Vec<B, Global>
) where
    Self: IndexedParallelIterator<Item = (A, B)>,

Unzips the results of the iterator into the specified vectors. The vectors are always truncated before execution begins. If possible, reusing the vectors across calls can lead to better performance since they reuse the same backing buffer.

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

Searches for some item in the parallel iterator that matches the given predicate, and returns its index. Like ParallelIterator::find_any, the parallel search will not necessarily find the first match, and once a match is found we'll attempt to stop processing any more.

Produces a new iterator with the elements of this iterator in reverse order.

pub fn with_min_len(self, min: usize) -> MinLen<Self>

Sets the minimum length of iterators desired to process in each thread. Rayon will not split any smaller than this length, but of course an iterator could already be smaller to begin with.

Sets the maximum length of iterators desired to process in each thread. Rayon will try to split at least below this length, unless that would put it below the length from with_min_len(). For example, given min=10 and max=15, a length of 16 will not be split any further.

) -> MapInit<Self, INIT, F> where
    F: Fn(&mut T, Self::Item) -> R + Sync + Send,
    R: Send,
    INIT: Fn() -> T + Sync + Send,

pub fn cloned<'a, T>(self) -> Cloned<Self> where
    Self: ParallelIterator<Item = &'a T>,
    T: 'a + Clone + Send,

    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).

pub fn reduce_with<OP>(self, op: OP) -> Option<Self::Item> where
    OP: Fn(Self::Item, Self::Item) -> Self::Item + Sync + Send, 

Reduces the items in the iterator into one item using op. If the iterator is empty, None is returned; otherwise, Some is returned.

pub fn fold<T, ID, F>(self, identity: ID, fold_op: F) -> Fold<Self, ID, F> where
    T: Send,
    F: Fn(T, Self::Item) -> T + Sync + Send,
    ID: Fn() -> T + Sync + 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.

pub fn fold_with<F, T>(self, init: T, fold_op: F) -> FoldWith<Self, T, F> where
    T: Send + Clone,
    F: Fn(T, Self::Item) -> T + Sync + Send,

    self,
    init: T,
    fold_op: F

    F: Fn(T, Self::Item) -> R + Sync + Send,
    R: Try<Ok = T> + Send, 

Performs a fallible parallel fold with a cloneable init value.

    F: Sync + Send + Fn(&Self::Item, &Self::Item) -> Ordering, 

Computes the maximum of all the items in the iterator with respect to the given comparison function. If the iterator is empty, None is returned; otherwise, Some(min) is returned.

pub fn max_by_key<K, F>(self, f: F) -> Option<Self::Item> where
    F: Sync + Send + Fn(&Self::Item) -> K,
    K: Ord + Send, 

Computes the item that yields the maximum value for the given function. If the iterator is empty, None is returned; otherwise, Some(item) is returned.

    P: Fn(&Self::Item) -> bool + Sync + Send,

    P: Fn(&Self::Item) -> bool + Sync + Send, 

Searches for the sequentially first item in the parallel iterator that matches the given predicate and returns it.

pub fn any<P>(self, predicate: P) -> bool where
    P: Fn(Self::Item) -> bool + Sync + Send, 

Searches for some item in the parallel iterator that matches the given predicate, and if so returns true. Once a match is found, we'll attempt to stop process the rest of the items. Proving that there's no match, returning false, does require visiting every item.

pub fn all<P>(self, predicate: P) -> bool where
    P: Fn(Self::Item) -> bool + Sync + Send,

Unzips the items of a parallel iterator into a pair of arbitrary ParallelExtend containers.

pub fn partition<A, B, P>(self, predicate: P) -> (A, B) where

    P: Fn(&Self::Item) -> bool + Sync + Send, 

Partitions the items of a parallel iterator into a pair of arbitrary ParallelExtend containers. Items for which the predicate returns true go into the first container, and the rest go into the second.
