async foundations about lang-team

[nikomatsakis]

Update 2020-07-27:

• Still working towards the Stream RFC, should schedule the meeting about it.
• boats proposed AsyncDrop, withdrawn but may come up later.

Update 2020-08-03:

• Ongoing work on the Stream trait, meeting likely next week

[nikomatsakis]

• Stream trait meeting planned for this Wednesday.

Update 2020-08-31:

• Had the meeting, no major blockers identified.
• Planning to open the RFC soon, but will add a plan for migration.

[nikomatsakis]

Update 2020-09-14:

• Discussed how the Stream RFC is really more of a "libs with lang consultation" RFC than anything else.
• Looking towards a lint similar to must_use but about values held live across yields.

[nikomatsakis]

Update 2020-09-21:

• Still waiting on Stream RFC.

[joshtriplett]

Stream RFC: rust-lang/rfcs#2996

[joshtriplett]

This shouldn't need further lang review until after that RFC has been merged and implemented.

Update 2020-10-07:

There is a Draft RFC available for a must_not_await lint.

Update 2021-04-06:

• Working on the async vision doc. Will be coordinating with lang team as we get a clearer idea of the roadmap and "shiny future" proposals.
• Another point of upcoming contact will be about the "async guiding principles", which -- at least at present -- look like they may be an interesting "specialization" of more general Rust language guiding principles. Good topic for a design meeting, perhaps.

[nikomatsakis]

Update 2021-07-07:

• The async vision doc has reached the end of its brainstorming period.
• We've been iterating towards what we believe to be the "shiny future", and there's a lot to discuss.
• You can find an overview of the current status in this diagram, which has links to more detailed design notes.

Most likely the best thing would be to have a design meeting to talk it over.
