## rkyv in action
```rust
use rkyv::{Aligned, Archive, ArchiveBuffer, Archived, WriteExt};
#[derive(Archive)]
struct Test {
int: u8,
string: String,
option: Option<Vec<i32>>,
}
fn main() {
let mut writer = ArchiveBuffer::new(Aligned([0u8; 256]));
let value = Test {
int: 42,
string: "hello world".to_string(),
option: Some(vec![1, 2, 3, 4]),
};
let pos = writer.archive(&value)
.expect("failed to archive test");
let buf = writer.into_inner();
let archived = unsafe { &*buf.as_ref().as_ptr().add(pos).cast::<Archived<Test>>() };
assert_eq!(archived.int, value.int);
assert_eq!(archived.string, value.string);
assert_eq!(archived.option, value.option);
}
```
