A little on the later end this week, but the meetup yesterday was just too distracting!
Compiler
Full report
This week there is one RFC, [#1191], entering its final comment
period. This RFC describes a proposal to separate the AST produced by
the parser from the one the compiler uses internally.
Language
Full report
It’s been a few weeks since the last report. To be honest, though,
there hasn’t been a lot of action in the language subteam, due to the
Mozilla work week, some vacations, and other factors.
This week, we’d like to move RFC #1150 into FCP:
This PR #873 about macros in types will remain in FCP for one more
week due to the fact that there was no time yet to talk it over in
depth. However, this will be the last week, or I will eat my hat (or
something):
-
FCP PR #873: Allow
macros in types. There has been some discussion but no firm decision
was reached.
Finally, the other RFC that was in FCP, #756, has been withdrawn. The
topic was expanded sugar for closure expressions, and the judgement
was that there wasn’t sufficient motivation to make the change at this
time. Perhaps later.
Libs
Full report
We’ve begun weekly video meetings with the entire subteam, which should increase
our bandwidth and enable more progress on new library initiatives. Over the next
week, we plan to discuss the pipeline for crates eventually heading into std,
and (relatedly) the fate of rust-lang crates. This week, though, we focused
mainly on existing business.
RFCs going into their final comment period:
-
FCP PR #1158:
RFC: Expand the std::net module
-
FCP PR #1174:
RFC for creation of
IntoRaw{Fd, Socket, Handle} trait to complement AsRaw*
PRs in final comment period:
Decisions from last week:
-
FCP PR #1055:
RFC for redirecting stdio of child processes to open file handles
-
FCP PR #1058:
RFC for replacing slice::tail()/init() with new methods
-
FCP PR #1102:
Rename connect to join
-
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.
Tools
Full report
This week the tools team picked up one RFC which should help mitigate
upstream breakage from the compiler updating lints. Cargo has a number of
outstanding PRs for new features such as cargo run --with,
project templates, and running cargo
concurrently. Emily has also performed an analysis of
the packaging status for Rust across various Linux distributions, and it looks
like we’ve got our work cut out for ourselves!
On the MSVC front the compiler will now probe for link.exe and has
briefly turned unwinding on by default, but this will likely be turned back off
soon. The codegen-units option now works on MSVC, though!
