Serde version

//! Versioning support for serde. //! When software are developped and used at the same time the data formats may change from one version to another and persisting data may be produced by a specific version and loaded by another version. //! Serde version provide a versioning feature for serde for the main use cases. //! See the guide here. //! Note 1: Requires the specialization feature. Note 2: Use the derive feature to generate the DeserializeVersioned implementation //!

Goals of Serde version

//! We aim at solving the case were a type or a set of types in a deserializer's data needs to be upgraded to their latest format. This is the case when a mandatory property was added or removed, or an existing property changed. //!

Non goals

//! This is based on types that can be upgraded individually. Types that needs to be upgraded together is way more complex to handle and usually relies on domain specific deserializer. //! So, these data format should be handle with specific Deserialize traits implementations.
