const SIZE: usize = 10;
c2rs_def!(
struct A{
DWORD var1;
DWORD var2;
union {
DWORD var4;
DWORD var5;
}var3;
struct {
u8 var7;
}var6;
DWORD array[SIZE];
};
struct B{
u8 var1;
};
// ....
);
let mut buffer = [1u8; 1024];
unsafe{
let mut buf = A::from_mut_bytes(buffer.as_mut_ptr());
let buf = buf.as_mut().unwrap();
buf.var1 = 10;
assert_eq!(10, buf.var1);
assert_eq!(10, buffer[0]);
let mut b = B::from_mut_bytes(buffer.as_mut_ptr()).as_mut().unwrap();
assert_eq!(10, b.var1);
