A persistent history tree for undo/redo
I don't know about complex, but here's an example
dipa makes it easy to efficiently delta encode large Rust data structures.
For diffing, I used json patch, which allows me to have a history of changes in an easy to serialize manner. There are other more efficient and space saving diffing libraries, such as this new one: https://github.com/chinedufn/dipa, however I found json patch is supported in a number of languages, easy to read and store in a db.
