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

Resources

Learning Materials

• The rkyv book covers the motivation, architecture, and major features of rkyv
• The rkyv discord is a great place to get help with specific issues and meet other people using rkyv

Documentation

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

Benchmarks

• The 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, which rkyv uses for validation
• ptr_meta, which rkyv uses for pointer manipulation
• 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>, }

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

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

let archived = unsafe { archivedroot::(&bytes[..]) }; asserteq!(archived.int, value.int); asserteq!(archived.string, value.string); asserteq!(archived.option, value.option);

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