The impl period
Two weeks ago, the “impl period” formally launched, and now has 37 working groups, with more to come! There’s a global Gitter channel (with IRC bridge), and dedicated channels for each working group.
This effort is intended for people with all experience levels and interests — there really is something for everyone, and the WG leads are putting a ton of work into mentoring. If you’re not sure what working group is right for you, drop by the main chatroom and introduce yourself, and we’ll help you find your way!
Highlights
We’ve had a steady stream of people joining up and finding their way to the various channels; welcome all! At this point most of the working groups are seeing sustained activity, especially around the compiler and libs work. The bindgen group has resulted in a new reviewer! And some early work is under way setting up policy for an expanded cookbook effort.
We also had our first impl days at RustFest; see below for more details!
Where help is most needed
- WG-cargo-native
- WG-infra-crater (Gitter channel is very lonely
️) - WG-infra-perf
