Crate 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 when only a small part of a struct has changed.

Macros

opaque_serde_diff

Implements SerdeDiff on a type given that it impls Serialize + Deserialize + PartialEq. This makes the type a “terminal” type in the SerdeDiff hierarchy, meaning deeper inspection will not be possible. Use the SerdeDiff derive macro for recursive field inspection.

Structs

Apply

A deserializable structure that will apply a sequence of diff commands to the target

Config

Configures creation of Apply and Diff

Diff

A serializable structure that will produce a sequence of diff commands when serialized. You can pass this to a serializer, or use the convenience method diff to pass your serializer along with old/new values to use when serializing the diff.

Enums

FieldPathMode

Configures how to serialize field identifiers
