Rust: Stabilizing naked functions

NewsBot · 3 July 2025 23:29

A new Rust blog post/announcement has been posted!

Rust 1.88.0 stabilizes the #[unsafe(naked)] attribute and the naked_asm! macro which are used to define naked functions.

A naked function is marked with the #[unsafe(naked)] attribute, and its body consists of a single naked_asm! call. For example:
/// SAFETY: Respects the 64-bit System-V ABI.
#[unsafe(naked)]
pub extern "sysv64" fn https://blog.rust-lang.org/2025/07/03/stabilizing-naked-functions/
