Trait rkyv::Unarchive

pub trait Unarchive<T: Archive<Archived = Self> + ?Sized>: Sized {
    pub fn unarchive(&self) -> T;
}

Converts a type back from its archived form.

This can be derived with Unarchive.

Examples

use rkyv::{Aligned, Archive, ArchiveBuffer, Archived, archived_value, Unarchive, Write};

#[derive(Archive, Debug, PartialEq, Unarchive)]
struct Test {
    int: u8,
    string: String,
    option: Option<Vec<i32>>,
}

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 { archived_value::<Test>(buf.as_ref(), pos) };

let unarchived = archived.unarchive();
assert_eq!(value, unarchived);
