Rust 1.99.0 Adds C Variadic Functions
2 min read
The Rust team released Rust 1.99.0, which stabilizes defining C-ABI variadic functions with "C" and "C-unwind" ABIs, letting developers write functions like libc::printf in Rust itself. The release also stabilizes size and alignment retrieval on raw pointers and updates Box::leak documentation to discourage round-trip unleaking, recommending Box::into_non_null instead.
