Rust-C Interoperability

The cluster discusses the capabilities, advantages, challenges, and tools for Foreign Function Interface (FFI) between Rust and C, including ABI stability, binding generation, and integration with existing C/C++ codebases.

Yes. But if people choose to , like me, go to a safer language that reduces congnitive load around bugs etc, it's easy enough to use the FFI of Rust to utilize any existing C libraries out there.

AFAIK Rust interops with C better than basically other other language other than C++.

Rust has C libraries which interface easily...

bryanlarsen Aug 7, 2015 View on HN

One advantage of Rust is its excellent C FFI. So as long as your dependencies have a C interface, you should be fine.

Is it possible to translate C into (unsafe) Rust while maintaining both human readability and link-level compatibility?

zozbot234 Jul 15, 2020 View on HN

Rust can bind to C libraries, as can many other languages.

Ygg2 Nov 11, 2015 View on HN

Rust can expose C interface. If your lang can talk to C, it can talk to Rust

PittleyDunkin Dec 23, 2024 View on HN

Normally I'd agree, but rust integration with C is so tight that this is of reduced concern.

choffee Mar 18, 2015 View on HN

Can you use a Rust library easily from all the current C code?

rubyfan Nov 23, 2017 View on HN

I might have missed it but is there a particular advantage Rust has over C in this specific use case? Performance, ease of interoperability, etc. or is it preference for Rust over C?
