A little later this week than usual, but here’s what’s happened over the past two weeks!
Friend of the Tree
@Gankro has nominated @tshepang for Friend of the Tree this week:
Over the last year Tshepang has landed over 100 improvements to our
documentation. Tshepang saw where documentation was not, and said “No. This
will not do.”
We should all endeavor to care about docs as much as Tshepang.
Compiler
Full report
We decided to accept RFC #1191, on adding a HIR to the compiler.
In addition, RFC #1211 has entered into final comment period. This
RFC describes a mid-level, simplified IR that will be constructed
after type-checking but be used to drive advanced analysis and code
generation.

Language
Full report
Two decisions were made since the last report:
- RFC #873 (macros in types) was accepted.
- RFC #1150 (re-exporting associated iteams with
use) was withdrawn.
One RFC is entering final comment period:
- RFC #1219: extending the
use syntax to allow renaming in group
imports.
- RFC #1214: clarifying rules for projections and well-formedness.
This is a soundness RFC that clarifies some of the language rules,
closing various soundness issues in the process. Some existing code
may no longer compile (full evaluation in progress); in any case,
the plan is to phase the changes in gradually.
Finally, we would like to call attention to one pending RFCs:
- RFC #1177: introducing an anonymous placeholder lifetime
'_.
There are some debates as to the best defaulting behavior and best
syntax; more input would be helpful.
Thanks!

Libs
Full report
A little belated this week and we slipped last week, so there’s definitely a few
things to catch up on! The libs team didn’t hold a triage meeting this week due
to many attendees having conflicts at the normal time, but we should make
progress on the FCP RFCs and new PRs next week. As a summary of last week’s actions:
RFCs going into their final comment period:
Decisions from last week:
-
FCP PR #1174:
RFC for creation of
IntoRaw{Fd, Socket, Handle} trait to complement AsRaw*
-
PR #26743:
Add a method
lines_any to BufRead
-
FCP PR #1158:
RFC: Expand the std::net module
- Postponed, pending some policy decisions about how to handle major new API
additions in std. We should have more details on this next week.
In the triage meeting last week we also discussed the story for adding new large
portions of functionality to the standard library (e.g. the std::net RFC), and
we will be posting our conclusions soon about this topic.
Tools
Full report
It’s been a bit since the last report, so here’s some of the highlights over the
past two weeks:
In other news the cargo install RFC is likely to go into FCP
soon, so be sure to keep an eye on it!
