serde (contract/attachment serialization)

Serde is the gold-standard framework for serializing and deserializing Rust data structures efficiently and safely.

Serde provides a high-performance ecosystem for translating Rust data structures into wire formats like JSON, BSON, and Postcard. By using Rust's derive macro system, it generates serialization logic at compile time (zero-cost abstraction) rather than relying on runtime reflection. This approach ensures type safety and maximum throughput for smart contracts and blockchain attachments where byte-level precision is non-negotiable. It currently supports over 25 data formats and integrates seamlessly with common crates like Chrono and SmallVec.
