Struct SliceParallelSource 

pub struct SliceParallelSource<'data, T> { /* private fields */ }

A parallel source over a slice. This struct is created by the par_iter() method on IntoExactParallelRefSource.

You most likely won’t need to interact with this struct directly, as it implements the ExactParallelSource and ExactParallelSourceExt traits, but it is nonetheless public because of the must_use annotation.

See also MutSliceParallelSource.

let input = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10];
let iter: SliceParallelSource<_> = input.par_iter();
let sum = iter.with_thread_pool(&mut thread_pool).sum::<i32>();
assert_eq!(sum, 5 * 11);

The slice element type must be Sync, so the following example doesn’t compile.

use std::cell::Cell;

let input = [Cell::new(1), Cell::new(2), Cell::new(3), Cell::new(4)];
let iter: SliceParallelSource<_> = input.par_iter();

Trait Implementations

impl<'data, T: Sync> ExactParallelSource for SliceParallelSource<'data, T>

type Item = &'data T

The type of items that this parallel source produces.

fn exact_descriptor( self, ) -> impl ExactSourceDescriptor<Item = Self::Item> + Sync

Returns an object that describes how to fetch items from this source.
