I know you guys are sick of Rust, but this is pretty cool stuff.

* C++ style name mangling
* unrolls loops

Try adding #[no_mangle] immidiately before the function.

0.15 Can C code call Rust code?
Yes. The Rust code has to be exposed via an extern declaration, which makes it C-ABI compatible. Such a function can be passed to C code as a function pointer or, if given the #[no_mangle] attribute to disable symbol mangling, can be called directly from C code.

—http://doc.rust-lang.org/complement-lang-faq.html#can-c-code-call-rust-code?

no_mangle - on any item, do not apply the standard name mangling. Set the symbol for this item to its identifier.

—http://doc.rust-lang.org/rust.html#miscellaneous-attributes

What's this about unrolling loops?

Yes, we all know C defines no ABI. What are you telling me for?

Note, every C program still has an ABI. Unlike C++ it's remarkably consistent per platform.
