Trait rayon::iter::IntoParallelRefIterator [−][src]
IntoParallelRefIterator
implements the conversion to a
ParallelIterator
, providing shared references to the data.
This is a parallel version of the iter()
method
defined by various collections.
This trait is automatically implemented
for I where &I: IntoParallelIterator
. In most cases, users
will want to implement IntoParallelIterator
rather than implement
this trait directly.
Associated Types
type Iter: ParallelIterator<Item = Self::Item>
[src]
The type of the parallel iterator that will be returned.
type Item: Send + 'data
[src]
The type of item that the parallel iterator will produce.
This will typically be an &'data T
reference type.
Required methods
fn par_iter(&'data self) -> Self::Iter
[src]
Converts self
into a parallel iterator.
Examples
use rayon::prelude::*; let v: Vec<_> = (0..100).collect(); assert_eq!(v.par_iter().sum::<i32>(), 100 * 99 / 2); // `v.par_iter()` is shorthand for `(&v).into_par_iter()`, // producing the exact same references. assert!(v.par_iter().zip(&v) .all(|(a, b)| std::ptr::eq(a, b)));
