Trait CollectIntoAllocVec 

pub trait CollectIntoAllocVec: IndexedParallelIterator {
    // Required method
    fn collect_into_alloc_vec<A: Allocator>(
        self,
        alloc: &A,
    ) -> A::Vec<Self::Item>;
}

Collects a parallel iterator into a buffer drawn from an Allocator.

The allocator’s counterpart to [IndexedParallelIterator::collect_into_vec], which targets a &mut Vec that a generic buffer is not. The buffer is sized to the iterator’s length, and its uninitialized capacity is written in parallel rather than zero-filled first.

Required Methods

fn collect_into_alloc_vec<A: Allocator>(self, alloc: &A) -> A::Vec<Self::Item>

Allocates a buffer holding one element per item and fills it with the iterator’s items.

use binius_compute::{CollectIntoAllocVec, GlobalAllocator};
use rayon::prelude::*;

let squares = (0..8usize).into_par_iter().map(|i| i * i);
let buffer = squares.collect_into_alloc_vec(&GlobalAllocator);
assert_eq!(&*buffer, &[0, 1, 4, 9, 16, 25, 36, 49]);

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
