On FreeBSD 15, the error code returned in this situation changed. It's now ENETUNREACH. I think that error code is reasonable, and it's documented for connect(2), so we should expect that it might be returned.
`cargotest` can only detect the worst offenders (like tests failing, or hard compiler errors / ICEs), but regardless, bumping `diesel` to a way more recent version hopefully contributes slightly towards helping us not break `diesel` if at all possible.
std supports redirecting stdio file descriptors.
- Make flush a noop since it is only for buffered writers. - Also forward fsync to datasync. UEFI does not have anything separate for metadata sync. Signed-off-by: Ayush Singh <[email protected]>
Since yesterday, the LLVM `main` branch should have working `f16` on all platforms that Rust supports; this will be LLVM version 22, so update how `cfg(target_has_reliable_f16)` is set to reflect this. Within the rust-lang organization, this currently has no effect. The goal is to start catching problems as early as possible in external CI that runs top-of-tree rust against top-of-tree LLVM, and once testing for the rust-lang bump to LLVM 22 starts. Hopefully this will mean that we can fix any problems that show up before the bump actually happens, meaning `f16` will be about ready for stabilization at that point (with some considerations for the GCC patch at [1] propagating).

stabilize `Peekable::next_if_map` (`#![feature(peekable_next_if_map)]`) # Stabilization report ## Summary `#![feature(peekable_next_if_map)]` is a variation of `next_if` on peekable iterators that can transform the peeked item. This creates a way to take ownership of the next item in an iterator when some condition holds, but put the item back when the condition doesn't hold. This pattern would otherwise have needed unwraps in many cases. [Tracking issue](rust-lang#143702) ### What is stabilized ```rust impl<I: Iterator> Peekable<I> { pub fn next_if_map<R>( &mut self, f: impl FnOnce(I::Item) -> Result<R, I::Item>, ) -> Option<R> { .. } pub fn next_if_map_mut<R>( &mut self, f: impl FnOnce(&mut I::Item) -> Option<R>, ) -> Option<R> { .. } } ``` Example usage adapted from the ACP: ```rust let mut it = Peekable::new("123".chars()); while let Some(digit) = it.next_if_map(|c| c.to_digit(10).ok_or(c)) { codepoint = codepoint * 10 + digit; } ``` or with `next_if_map_mut`: ```rust let mut it = Peekable::new("123".chars()); while let Some(digit) = iter.next_if_map_mut(|c| c.to_digit(10)) { line_num = line_num * 10 + digit; } ``` Note that the major difference here is that `next_if_map_mut` does not get owned items from the iterator, but mutable references. With that api, the closure can return an `Option` which avoids an `ok_or`. This may require cloning or copying the iterator elements, so if that is expensive, the owned version, `next_if_map`, may be preferable. ### Nightly use At the moment, this feature is barely used in nightly, though I've found multiple good uses for it in my own projects, hence my pushing for stabilization. It makes the kind of patterns used in recursive descent parsing super concise and maybe with its stabilization it will find more use. ### Test coverage Besides a quite comprehensive doctest, this feature is tested (including panicking in the closure) here: https://github.com/rust-lang/rust/blob/c880acdd3171dfafdb55be8cd9822a857e99348d/library/coretests/tests/iter/adapters/peekable.rs#L275-L359 ## History - ACP: rust-lang/libs-team#613 accepted with rust-lang/libs-team#613 (comment) - implementation: rust-lang#143725 with tests, and no issues reported since july. ## Acknowledgments ACP, implementation and tracking issue for this feature all by @kennytm <3
adding Ordering enum to minicore.rs, importing minicore in "tests/assembly-llvm/rust-abi-arg-attr.rs" test file this adds the `Ordering` enum to `minicore.rs`. consequently, this updates `tests/assembly-llvm/rust-abi-arg-attr.rs` to import `minicore` directly. previously, this test file contained traits like `Copy` `Clone` `PointeeSized`, which were giving a duplicate lang item error, so replace those by importing `minicore` completely.

Reword the collect() docs Update the `Iterator::collect` docs so they explain that the return type, not the iterator itself, determines which collection is built. Follow up on rust-lang#121140

…lacrum Bump `diesel` to the most recent commit in `cargotest` `cargotest` can only detect the worst offenders (like tests failing, or hard compiler errors / ICEs), but regardless, bumping `diesel` to a way more recent version hopefully contributes slightly towards helping us not break `diesel` if at all possible. That is, AFAIUI, this will not help catch [#t-compiler/prioritization/alerts > rust-lang#149845 Diesel stops building with nightly-2025-12-10 @ 💬](https://rust-lang.zulipchat.com/#narrow/channel/245100-t-compiler.2Fprioritization.2Falerts/topic/.23149845.20Diesel.20stops.20building.20with.20nightly-2025-12-10/near/566975273) because we cap-lints to `warn` in `cargotest`.

Closing this PR as its purpose has been served, but it would also be a good basis for a real rollup to come after #150951 (and an intervening rollup=never PR). |
