`const if` to supress instantiation/codegen of unreachable branches

29

Currently there's a suboptimal interaction between const asserts and const generics. A more general function that is valid for all N cannot call a function that asserts at compile time...

Support for non-blocking and best-effort zero-copy `io::copy`

# Proposal ## Problem statement It would be useful to have a version of `io::copy` that can use: - splice or sendfile, some of the existing optimizations have to be...

I realize that given the `nsTArray` mentions in the documentation this is probably out of scope, so feel free to just close this, but here I go anyway: The conversion...

from_env causes io-unsafety in child processes

4

(copied from https://github.com/rust-lang/rust/pull/113730#issuecomment-1869013070) These lines seem questionable: https://github.com/rust-lang/jobserver-rs/blob/b4bc5db730a93d01cf8d0d868a2b6f553f535d2d/src/unix.rs#L152-L153 They lead the fds not being available to child processes by default (unless reverted by `Client::configure`) but [from_env_ext()](https://github.com/rust-lang/jobserver-rs/blob/b4bc5db730a93d01cf8d0d868a2b6f553f535d2d/src/lib.rs#L264-L296) does not remove the...

Currently on my desktop the dashboard charts look like this  Due to the exponential downwards trend each incremental change becomes more more difficult to distinguish. Changing the aspect ratio...

Dynamic linking

Dynamically linking against libstd and possibly other libraries can significantly reduce binary size (even though not overall size). This has of course the caveat that rust has no stable ABI...

Language vs. implementation threat models and implications for TypeId collision resistance

From #129014 and #10389 > If you instead want to argue that the lang team should change its mind, please open a new issue and gather arguments in favor of...

/proc/self/maps ioctl interface for more efficient memory map queries

1

The 6.11 linux kernel added a [new ioctl interface](https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=c10cb9148e51) to the maps file that allows more efficient querying of the mapped memory ranges. Depending on how much time is spent...

use stores of the correct size to set discriminants

Resolves an old HACK /FIXME. Note that I haven't worked much with codegen so I'm not sure if I'm using the functions correctly and I was surprised seeing out-of-range values...
