Struct orx_concurrent_iter::ConIterOfVec

pub struct ConIterOfVec<T: Send + Sync + Default> { /* private fields */ }

A concurrent iterator over a vector, consuming the vector and yielding its elements.

Implementations

impl<T: Send + Sync + Default> ConIterOfVec<T>

pub fn new(vec: Vec<T>) -> Self

Consumes and creates a concurrent iterator of the given vec.

Trait Implementations

impl<T: Send + Sync + Default> AtomicIter<T> for ConIterOfVec<T>

fn counter(&self) -> &AtomicCounter

Returns a reference to the underlying advanced item counter.

fn get(&self, item_idx: usize) -> Option<T>

Returns the item_idx-th item that the iterator yields; returns None if the iterator completes before.

fn fetch_n(&self, n: usize) -> impl NextChunk<T>

Returns an iterator of the next n consecutive items that the iterator yields. It might return an iterator of less or no items if the iteration does not have sufficient elements left.

fn for_each_n<F: FnMut(T)>(&self, chunk_size: usize, f: F)

Applies the function f to each element of the iterator concurrently.

fn enumerate_for_each_n<F: FnMut(usize, T)>(&self, chunk_size: usize, f: F)

Applies the function f to each element and its corresponding index of the iterator concurrently. It may be considered as the concurrent counterpart of the chain of enumerate and for_each_n calls.

fn fold<B, F: FnMut(B, T) -> B>(&self, chunk_size: usize, initial: B, f: F) -> B

Folds the elements of the iterator pulled concurrently using fold function.

fn fetch_one(&self) -> Option<Next<T>>

Returns the next item that the iterator yields; returns None if the iteration has completed.

impl<T: Send + Sync + Default> AtomicIterWithInitialLen<T> for ConIterOfVec<T>

fn initial_len(&self) -> usize

Returns the initial length of the atomic iterator.

fn fetch_n_with_exact_len( &self, n: usize ) -> NextManyExact<T, impl ExactSizeIterator<Item = T>>

Returns an iterator of the next n consecutive items that the iterator together with an exact size iterator. It might return an iterator of less or no items if the iteration does not have sufficient elements left.

impl<T: Send + Sync + Default> ConcurrentIter for ConIterOfVec<T>

type Item = T

Type of the items that the iterator yields.

fn next_id_and_value(&self) -> Option<Next<Self::Item>>

Advances the iterator and returns the next value together with its enumeration index.

fn next_chunk(&self, chunk_size: usize) -> impl NextChunk<Self::Item>

Advances the iterator chunk_size times and returns an iterator of at most chunk_size consecutive next values. Further, the beginning enumeration index of the yielded values is returned.

fn for_each_n<F: FnMut(Self::Item)>(&self, chunk_size: usize, f: F)

Applies the function fun to each element of the iterator concurrently.

fn enumerate_for_each_n<F: FnMut(usize, Self::Item)>( &self, chunk_size: usize, f: F )

Applies the function fun to each index and corresponding element of the iterator concurrently.

fn fold<B, Fold>(&self, chunk_size: usize, neutral: B, fold: Fold) -> B

where Fold: FnMut(B, Self::Item) -> B,

Folds the elements of the iterator pulled concurrently using fold function.

fn next(&self) -> Option<Self::Item>

Advances the iterator and returns the next value.

fn values(&self) -> ConIterValues<'_, Self>

where Self: Sized,

Returns an Iterator over the values of elements of the concurrent iterator.

fn ids_and_values(&self) -> ConIterIdsAndValues<'_, Self>

where Self: Sized,

Returns an Iterator over the ids and values of elements of the concurrent iterator.

fn for_each<Fun: FnMut(Self::Item)>(&self, fun: Fun)

Applies the function fun to each element of the iterator concurrently.

fn enumerate_for_each<Fun: FnMut(usize, Self::Item)>(&self, fun: Fun)

Applies the function fun to each index and corresponding element of the iterator concurrently. It may be considered as the concurrent counterpart of the chain of enumerate and for_each calls.

impl<T: Debug + Send + Sync + Default> Debug for ConIterOfVec<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T: Send + Sync + Default> ExactSizeConcurrentIter for ConIterOfVec<T>

fn len(&self) -> usize

Returns the exact remaining length of the concurrent iterator.

fn next_exact_chunk( &self, chunk_size: usize ) -> Option<NextManyExact<Self::Item, impl ExactSizeIterator<Item = Self::Item>>>

Returns the next chunk with the requested chunk_size:

fn is_empty(&self) -> bool

Returns true if the iterator is empty.

impl<T: Send + Sync + Default> From<Vec<T>> for ConIterOfVec<T>

fn from(vec: Vec<T>) -> Self

Consumes and creates a concurrent iterator of the given vec.
