# Resources


## Learning Materials


- The [rkyv book](https://rkyv.github.io/rkyv) covers the motivation, architecture, and major
  features of rkyv
- The [rkyv discord](https://discord.gg/65F6MdnbQh) is a great place to get help with specific issues and meet
  other people using rkyv

## Documentation


- [rkyv](https://docs.rs/rkyv), the core library
- [rkyv_dyn](https://docs.rs/rkyv_dyn), which adds trait object support to rkyv
- [rkyv_typename](https://docs.rs/rkyv_typename), a type naming library

## Benchmarks


- The [rust serialization benchmark](https://github.com/djkoloski/rust_serialization_benchmark) is a
  shootout style benchmark comparing many rust serialization solutions. It includes special
  benchmarks for zero-copy serialization solutions like rkyv.

## Sister Crates


- [bytecheck](https://github.com/rkyv/bytecheck), which rkyv uses for validation
- [ptr_meta](https://github.com/rkyv/ptr_meta), which rkyv uses for pointer manipulation
- [rend](https://github.com/rkyv/rend), which rkyv uses for endian-agnostic features

# Example


```rust
use rkyv::{
    archived_root,
    ser::{serializers::AllocSerializer, Serializer},
    Archive, Deserialize, Infallible, Serialize,
};

#[derive(Archive, Deserialize, Serialize, Debug, PartialEq)]

struct Test {
    int: u8,
    string: String,
    option: Option<Vec<i32>>,
}

let value = Test {
    int: 42,
    string: "hello world".to_string(),
    option: Some(vec![1, 2, 3, 4]),
};

let mut serializer = AllocSerializer::<256>::default();
serializer.serialize_value(&value).unwrap();
let bytes = serializer.into_serializer().into_inner();

let archived = unsafe { archived_root::<Test>(&bytes[..]) };
assert_eq!(archived.int, value.int);
assert_eq!(archived.string, value.string);
assert_eq!(archived.option, value.option);

let deserialized: Test = archived.deserialize(&mut Infallible).unwrap()
assert_eq!(deserialized, value);
```
