rkyv (archive) is a zero-copy deserialization framework for Rust.

API Documentation

• rkyv, the core library
• rkyv_dyn, which adds trait object support to rkyv
• rkyv_typename, a type naming library

Book

• The rkyv book covers the motivation and architecture of rkyv

Sister Crates:

• bytecheck, which rkyv uses for validation
• ptr_meta, which rkyv uses for pointer manipulation

rkyv in action

```rust use rkyv::{ archived_root, de::deserializers::AllocDeserializer, ser::{serializers::WriteSerializer, Serializer}, AlignedVec, Archive, Deserialize, Serialize, };

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

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

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

let mut serializer = WriteSerializer::new(AlignedVec::new()); serializer .serializevalue(&value) .expect("failed to serialize value"); let buf = serializer.intoinner();

let archived = unsafe { archivedroot::(buf.asref()) }; asserteq!(archived.int, value.int); asserteq!(archived.string, value.string); assert_eq!(archived.option, value.option);

let mut deserializer = AllocDeserializer; let deserialized = archived .deserialize(&mut deserializer) .expect("failed to deserialize value"); assert_eq!(deserialized, value); ```
