# Rexa



  

  

  

   



A library implementing [OCapN](https://github.com/ocapn/ocapn).

## Progress

- [ ] Async runtime agnostic

- [ ] Test with [ocapn-test-suite](https://github.com/ocapn/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`, or should we use a message channel?

  - [ ] Figure out how to deal with promise pipelining

  - [ ] Third-party handoffs

  - Operations:

    - [x] `op:start-session`

    - [x] `op:deliver-only`

    - [x] `op:deliver`

    - [ ] `op:pick`

    - [x] `op:abort`

    - [ ] `op:listen`

    - [ ] `op:gc-export`

    - [ ] `op:gc-answer`

  - Bootstrap:

    - [x] `fetch`

    - [ ] `deposit-gift`

    - [ ] `withdraw-gift`

  - Promises:

    - [x] `fulfill`

    - [x] `break`

- Netlayers:

  - [ ] Onion Netlayer ([arti](https://gitlab.torproject.org/tpo/core/arti)'s onion service support is shaky right now)

  - [ ] Manage multiple transport types using some sort of netlayer manager struct?

- Locators:

  - [ ] Deserialize from URI
