  • The list of blocking issues is shrinking!

  • Two major issues have had signficant work done on them:

    • nikomatsakis posted a PR which closes a number of lifetime related issues.
    • tmandry is working on shrinking the size of futures.
  • Work is commencing on the “async book” which will help explain how async I/O works and the async-await feature in particular.

  • Many more tests need to be written around the feature.

    • This might be a good way to get involved with the working group!
