Pre-RFC: BTF Relocations for Rust
A series of discussions on the Rust Internals forum introduces a pre-RFC for BTF (BPF Type Format) relocations, proposing a new #[btf_preserve_access] attribute. This change aims to improve the compatibility of Rust with BPF (Berkeley Packet Filter) targets by preserving access to aggregate types during compilation. The proposal could significantly impact how Rust handles type layouts, especially in systems programming contexts where BPF is heavily utilized.
