Good day, and welcome to Rust for August sixth, twenty twenty-six.
Today's biggest thread is target features and ABI correctness. Ralf Jung opened two related pull requests: one, one six zero five nine three, turns ABI-controlling target features into a target modifier so mismatches get caught at compile time instead of causing silent miscompiles. The second, one six zero six one…
Second theme: trait system and type system cleanup. Jack H's PR one six zero five two zero adds tests that close out seven long-standing specialization bugs, some dating back to twenty seventeen. Ada four A's rename of "outlives predicate" to "outlives clause" in PR one six zero three four three, and Mejrs' removal…
Third, safety and correctness fixes in the standard library and diagnostics: dev-nex-en's fix for a stack buffer overflow in Windows junction point handling, PR one five eight one four seven, closes a real memory-safety bug. And no-mangle generic items moving from a lint warning to a hard error, PR one five four…
As usual, Jonathan Brouwer's rollup PRs bundled most of this work into batches of thirteen to twenty-five merges each, the normal mechanism for landing verified changes quickly.
