Opening Keynote with Carl Lerche and Alice Ryhl
summary
Historical recount of how Rust lands async await as a zero-cost async/await trait breakthrough, the pragmatic fixes that made Tokio fast (poll/schedule elimination), and concrete new runtime features: partial IO_uring-for-files support, a single-threaded local runtime that matches threaded behavior, per-thread timers, multi-queue spawn-blocking, and work-stealing fixes that reduce pathological latencies. Also a concrete higher-level project, Toasty ORM with built-in query engine, plus advocacy for macros and AI tooling that shrink the Rust onboarding curve and improve generated code quality.
