(Rust) All-Hands 2026 Retrospective
↗
Several long-standing technical blockers saw progress, including a potential unblocking of rustc_public and a path forward for cargo-semver-checks on cross-crate analysis via rustdoc JSON. The governance sessions—covering maintainer disempowerment, RFC process reform drawing on TC39 ideas, and project funding—signal active work on the coordination and sustainability problems that directly affect contributor experience and project velocity.

Technical sessions advanced discussions on const generics, const traits, field projections, reborrowing, in-place initialization, SIMD, allocators, the Sized Hierarchy, auto traits, and rustc as a library.
Interoperability was a major focus, with in-person collaboration between the Rust Project and both Rust for Linux and Rust for CPython, plus sessions on Crubit and on combining LLVM IR with Rust MIR for safer interop.
Governance sessions addressed maintainer disempowerment, potential RFC process changes inspired by TC39, and improving how the project coordinates and communicates around goals and funding.
