Function chunk 

pub fn chunk<T>(arr: &[T], chunk_size: usize) -> Vec<Vec<T>>
where
    T: Clone,

将数组分块/Chunk an array into smaller arrays

参数/Arguments

• arr - 要分块的数组/The array to chunk
• chunk_size - 每个块的大小/The size of each chunk

返回值/Returns

包含分块结果的 Vec<Vec<T>>/A vector of vectors containing the chunks

示例/Examples

use slice_reducer::chunk;
let arr = vec![1, 2, 3, 4, 5];
let chunks = chunk(&arr, 2);
assert_eq!(chunks, vec![vec![1, 2], vec![3, 4], vec![5]]);

注意/Notes

• 如果 chunk_size 为 0，返回空向量/If chunk_size is 0, returns empty vector
• 最后一个块可能小于 chunk_size/Last chunk may be smaller than chunk_size
