This Week in Rust 626
Official
The 2025 State of Rust Survey is now open for participation to gather insights into the global Rust community.
The Rust Project's GSoC 2025 concludes with 18 successful projects, bringing significant advancements to compiler features (autodiff, safety contracts, parallel frontend), Cargo tooling, infrastructure (rustup, bors), and core library components (libc, std::arch intrinsics).
Field projection updates detail standardizing decomposition, restricting Field Representing Types (FRTs) to single fields for simpler design and enhanced utility (e.g., for kernel), simplifying the `Project` trait, and addressing safety concerns.
Ongoing work on custom reference field projections details progress on `pin_ergonomics` compatibility, explores syntax and design for shared/exclusive projections, container/pointer interactions, enum support, and initial compiler implementation of Field Representing Types.

Explore a conceptual redesign of the Rust compiler's incremental system, leveraging "atomic levels" and "data dependencies" to significantly reduce redundant rebuilds across `check`, `clippy`, and `build` steps.
A set of traits defining a generalized "place" abstraction for smart pointers, enabling fine-grained sub-place projections, custom borrow kinds, and controlled memory operations.
Proposes a mental model for `Pin` as a manager for a hypothetical `&'static weak T` reference, enforcing invariants like `!Unpin` and `Drop` execution before deallocation.
