rkyv is a zero-copy deserialization framework for Rust that serializes data into an archived format that can be accessed directly in-place without deserialization. It provides safe, validated access to archived data and derives Archive/Serialize/Deserialize implementations for Rust types.

Use cases

• serialize rust structs to bytes with zero-copy access
• load large serialized datasets without deserialization overhead
• fast serialization for games and high-performance applications
• no_std embedded serialization
• compare rust serialization solutions for benchmarks

When to choose

• you need extremely fast deserialization or in-place access to serialized data
• you're working in Rust and want derive-based serialization
• you need no_std support or minimal resource usage

When to avoid

• you need cross-language serialization interop like JSON or protobuf
• your data is small and serialization speed is not a bottleneck
• you need human-readable formats
