Exploring New Rust Pre-RFCs: Trait Method Exclusion and BTF Relocations — Rust Internals

Two new pre-RFCs are under discussion in the Rust community. The first proposes allowing exclusion of trait methods for unsatisfiable where bounds, which could simplify trait implementations. The second introduces BTF relocations, adding a #[btf_preserve_access] attribute for aggregate types, aimed at improving compatibility with BPF targets. These discussions could lead to significant changes in how Rust handles trait bounds and type layouts, affecting future Rust projects targeting specific platforms.

Building a Bare-Metal ARM64 Hypervisor in No-Std Rust — Rust Users Forum

A Rust developer has successfully built a bare-metal Type-1 hypervisor for ARM's S-EL2 using no_std Rust, replacing Google's Hafnium SPMC. This 30K lines project demonstrates Rust's capability to handle low-level, performance-critical tasks without relying on the standard library. It highlights Rust's potential in systems programming, particularly in secure environments, and serves as an inspiration for projects requiring high performance and security.
