Trait Implementations

impl IndexedParallelIterator for PacketBatchParIterMut<'_>

fn len(&self) -> usize

Produces an exact count of how many items this iterator will produce, presuming no panic occurs.

fn drive<C: Consumer<Self::Item>>(self, consumer: C) -> C::Result

Internal method used to define the behavior of this parallel iterator. You should not need to call this directly.

fn with_producer<CB: ProducerCallback<Self::Item>>( self, callback: CB, ) -> CB::Output

Internal method used to define the behavior of this parallel iterator. You should not need to call this directly.

fn by_exponential_blocks(self) -> ExponentialBlocks<Self>

Divides an iterator into sequential blocks of exponentially-increasing size.

fn by_uniform_blocks(self, block_size: usize) -> UniformBlocks<Self>

Divides an iterator into sequential blocks of the given size.

fn collect_into_vec(self, target: &mut Vec<Self::Item>)

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

fn unzip_into_vecs<A, B>(self, left: &mut Vec<A>, right: &mut Vec<B>)

where Self: IndexedParallelIterator<Item = (A, B)>, A: Send, B: Send,

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

fn zip<Z>(self, zip_op: Z) -> Zip<Self, <Z as IntoParallelIterator>::Iter>

where Z: IntoParallelIterator, <Z as IntoParallelIterator>::Iter: IndexedParallelIterator,

Iterates over tuples (A, B), where the items A are from this iterator and B are from the iterator given as argument. Like the zip method on ordinary iterators, if the two iterators are of unequal length, you only get the items they have in common.

fn zip_eq<Z>(self, zip_op: Z) -> ZipEq<Self, <Z as IntoParallelIterator>::Iter>

where Z: IntoParallelIterator, <Z as IntoParallelIterator>::Iter: IndexedParallelIterator,

where I: IntoParallelIterator<Item = Self::Item>, <I as IntoParallelIterator>::Iter: IndexedParallelIterator,

Interleaves elements of this iterator and the other given iterator. Alternately yields elements from this iterator and the given iterator, until both are exhausted. If one iterator is exhausted before the other, the last elements are provided from the other.

where 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.

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

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

fn with_max_len(self, max: usize) -> MaxLen<Self>

Sets the maximum length of iterators desired to process in each rayon job. 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.

impl<'a> ParallelIterator for PacketBatchParIterMut<'a>

fn cloned<'a, T>(self) -> Cloned<Self>

where T: 'a + Clone + Send, Self: ParallelIterator<Item = &'a T>,

fn copied<'a, T>(self) -> Copied<Self>

where T: 'a + Copy + Send, Self: ParallelIterator<Item = &'a T>,

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).

fn reduce_with<OP>(self, op: OP) -> Option<Self::Item>

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

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.

fn fold_with<F, T>(self, init: T, fold_op: F) -> FoldWith<Self, T, F>

where F: Fn(T, Self::Item) -> T + Sync + Send, T: Send + Clone,

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

Computes the minimum 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.

where K: Ord + Send, F: Sync + Send + Fn(&Self::Item) -> K,

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

fn max_by<F>(self, f: F) -> Option<Self::Item>

where 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(max) is returned.

fn max_by_key<K, F>(self, f: F) -> Option<Self::Item>

where K: Ord + Send, F: Sync + Send + Fn(&Self::Item) -> K,

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.

where C: IntoParallelIterator<Item = Self::Item>,

Takes two iterators and creates a new iterator over both.

fn find_any<P>(self, predicate: P) -> Option<Self::Item>

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

Searches for some item in the parallel iterator that matches the given predicate and returns it. This operation is similar to find on sequential iterators but the item returned may not be the first one in the parallel sequence which matches, since we search the entire sequence in parallel.

fn find_first<P>(self, predicate: P) -> Option<Self::Item>

where 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.

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.

fn all<P>(self, predicate: P) -> bool

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

Tests that every item in the parallel iterator matches the given predicate, and if so returns true. If a counter-example is found, we’ll attempt to stop processing more items, then return false.
