Or make a thin wrapper that is just safe functions that inside just have an unsafe block with the C ABI function. Even if rust had a stable ABI, you would still need that unsafe block.
minus-squareFizzyOrange@programming.devlinkfedilinkarrow-up1·3 days agoI think there are some crates that wrap the unsafe code for you, e.g. https://github.com/rodrimati1992/abi_stable_crates/ (I haven’t ever tried it).
