[][src]Crate rawpointer

Rawpointer adds extra utility methods to raw pointers *const T, *mut T and NonNull<T>.

Features include:

use rawpointer::PointerExt;

unsafe {
    // In this example:
    // Use .post_inc() to iterate and overwrite the first four
    // elements of the array.

    let mut xs = [0; 16];
    let mut ptr = xs.as_mut_ptr();
    let end = ptr.offset(4);
    let mut i = 0;
    while ptr != end {
        *ptr.post_inc() = i;
        i += 1;
    }
    assert_eq!(&xs[..8], &[0, 1, 2, 3, 0, 0, 0, 0]);
}
