Rexa

A library implementing OCapN.

Progress

• Async runtime agnostic
• Test with ocapn-test-suite (partially working; requires OnionNetlayer to work)
• Syrup:
  • #[derive(Serialize, Deserialize)] (partial; missing enums, some other features)
  • Design better way of handling enums
• CapTP:
  • Crossed Hellos mitigation
  • Figure out ideal way to prevent reader/writer generics from infecting everything else
    • Right now, it's difficult to write code that can use multiple netlayers at once
  • Should we store locally exported objects as Arc<dyn Object>, or should we use a message channel?
  • Figure out how to deal with promise pipelining
  • Third-party handoffs
  • Operations:
    • op:start-session
    • op:deliver-only
    • op:deliver
    • op:pick
    • op:abort
    • op:listen
    • op:gc-export
    • op:gc-answer
  • Bootstrap:
    • fetch
    • deposit-gift
    • withdraw-gift
  • Promises:
    • fulfill
    • break
• Netlayers:
  • Onion Netlayer (arti's onion service support is shaky right now)
  • Manage multiple transport types using some sort of netlayer manager struct?
• Locators:
  • Deserialize from URI

Examples

• Sneedchat

Etymology
