Expand description

Creates an immutable slice from the terminated array by finding it’s last element. Returns a slice NOT INCLUDING the last element. Maximum length is usize::MAX

Safety

ptr must be valid, properly alligned.

let arr: [u8; 4] = [1, 2, 3, 0];
let terminated = unsafe { terminated_array(arr.as_ptr(), &0) };
assert_eq!(terminated, &[1, 2, 3]);
