Since I apparently forgot to post a blog post last week, this blog post covers two lang-team triage meetings: [2019-11-14] and [2019-11-21]. Recordings from both meetings are also available.

Updates on shepherded items

Here is a list of the "shepherded items" that the lang team is tracking, along with weekly updates on the latest developments.

• const-eval
  • there is progress towards extending the set of expressions permitted in constants to include &mut borrows, if/match, and loops.
• project-ffi-unwind
  • current status: currently evaluating whether "C" functions should permit unwinding by default
  • trying to get measurements of the impact on code size
  • prototyped the plan in a rustc branch, but needs a few updates and to be executed on a representative code base (likely Fuchsia)
• Coherence can be bypassed by an indirect impl for a trait object
  • did a crater run of the proposal but have only partially analyzed the impact
• grammar working group — qmx
  • no updates this week
• ! type and fallback — centril
  • ! is stable on nightly!

About the lang-team meetings

The lang-team triage meetings are held weekly on Zoom (see our meeting calendar). Anyone is welcome to come and observe. We make a "best effort" to record the meetings though technical issues sometimes intervene.
