Function rustml::vectors::copy_memory

pub fn copy_memory<T: Copy>(dst: &mut [T], src: &[T], n: usize) -> usize

Copies elements from src to dst.

This function copies at most n elements from src to dst. If n is larger than the size of src or dst min(src.len(), dst.len()) elements are copied. The function returns the number of elements that have been copied.

Example

use rustml::vectors::*;

let a = vec![1, 2, 3, 4];
let e = vec![1, 2, 3, 0];
let mut b = vec![0, 0, 0, 0];

copy_memory(&mut b, &a, 3);
assert_eq!(b, e);

Implementation details

This function uses the C function call memcpy to copy the memory.
