Examples

use core::ptr::addr_of;
use nstd_sys::core::ptr::{nstd_core_ptr_get, nstd_core_ptr_new};

unsafe {
    const VALUE_SIZE: usize = core::mem::size_of::<u32>();
    let x = 45u32;
    let ptr = nstd_core_ptr_new(addr_of!(x).cast(), VALUE_SIZE).unwrap();
    assert!(*nstd_core_ptr_get(&ptr).cast::<u32>() == x);
}
