Trait rayon::iter::IntoParallelRefIterator

source · 
pub trait IntoParallelRefIterator<'data> {
    type Iter: ParallelIterator<Item = Self::Item>;
    type Item: Send + 'data;

    fn par_iter(&'data self) -> Self::Iter;
}
Expand description

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.

Required Associated Types§

The type of the parallel iterator that will be returned.

The type of item that the parallel iterator will produce. This will typically be an &'data T reference type.

Required Methods§

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)));
