I thought the gov wrote this, just a joke huh

Yeah, and there’s no plan to stabilize the ABI because it’s developing.

You can use C ABI for some data formats, but you’re limited on what you can use (mostly primitives). There’s a crate stable-abi or abi-stable that provides a way to do things to keep it stable, but since it’s external crate it has limitations.

I know it’s frustrating because I am writing something in rust that loads functions in runtime. I thought it’d be easy because programs written in C do it all the time. Rust gives a lot of advantages but working on dynamic loading hasn’t been fun. And there aren’t a lot of resources about this either.

IIRC Same compiler version doesn’t mean the ABI will be the same. Each compilation may produce different representation of data structures in the binary. Depending on the optimization and other things.
