Rust 1.99 stabilizes defining C-ABI variadic functions

blog.rust-lang.org Editor score 7/10

Rust 1.99 stabilizes defining variadic functions with the C and C-unwind ABIs, extending Rust from calling external variadic functions to implementing them. This matters for engineers integrating Rust with C interfaces.

What

• Rust 1.99 stabilizes defining variadic functions with the C and C-unwind ABIs.

How

• Rust functions can now accept variable argument lists, and raw-pointer layout APIs for size and alignment are stabilized.

Why it matters

• C-ABI variadics let systems engineers write this class of C-compatible interface directly in Rust.
