serde-diff

A small helper that can 1. Serialize the fields that differ between two structs of the same type 2. Apply previously serialized field differences to other structs.

The SerdeDiff trait impl can serialize field paths recursively, greatly reducing the amount of data that needs to be serialized.

TODO: crates.io badge

Status

Works for most basic use-cases. Includes derive macro, some standard library type implementations and deep serde integration. Supports diffing Vec. Supports both text and binary serde formats.

Usage

On a struct: ```

[derive(SerdeDiff, Serialize, Deserialize)]

```

Serialize & apply differences:

bincode let bincode_data = bincode::serialize(&Diff::serializable(&old, &new)).unwrap(); bincode::config() .deserialize_seed(Apply::deserializable(&mut target), &bincode_data) .unwrap(); serde_json let mut deserializer = serde_json::Deserializer::from_str(&json_data); Apply::apply(&mut deserializer, &mut target).unwrap();
