Roadmap for 0.2.0

[nugmanoff]

Hey @ObuchiYuki @heckj, here's the draft for roadmap for the 0.2.0 release as I see it. I would love to have your input on this one to decide what we need to prioritize/add/remove.

I will be updating this message as we proceed with the discussion.

Following are improvements that I think should be included in the next release:

• [ ] Expose iterator directly from Rust
  • Basically it means wrapping iter() method in Rust directly. Right now iteration is pretty naively implemented – it just collects all values upfront and then iterates over them. Direct iterator wrapping will enable us to have better support for Sequence, Collection types on the Swift side.
• [ ] Verify interoperability with other language bindings. Probably start by interacting with simple yjs-based web app.
• [ ] Improve usability of Attributes and Embeds to allow more streamlined experience of working with rich text (think – NSAttributedString)
• [ ] Implement lib0
  • @ObuchiYuki already ported here most of it. We'd just need to implement it as top-level coder and fully conform to Codable.
• [ ] Leverage lib0 encoding/decoding to pass complex types instead of JSON String.
  • We already started discussing it with Joe, I think we can continue it there as well https://github.com/y-crdt/yswift/issues/7
• [ ] Nested types
• [ ] Implement YProtocol
  • Same as with lib0, we can reuse Yuki's implementation

Below are things that I think can wait:

• [ ] Separate TransactionMut & Transaction in Rust wrapper
  • [ ] Make Concurrency support more fine-grained
  • Right now all transactions that are created through Rust wrapper are TransactionMut – it is done so for simplicity purposes. But it does come at a cost, because TransactionMut does more job than just Transaction so it makes sense to separate between them for the Rust wrapper/YSwift as well.
• [ ] Transaction Events
• [ ] Undo/Redo Manager
• [ ] Awareness
• [ ] Integration with Lexical
