Rust FFI: The Wrong Way? Ralph Minderhoud

Webb11 apr. 2024 · The intention of the library is to enable writing plugins for LADSPA hosts in Rust. Since LADSPA is a C API, it would be nice to provide some kind of Rusty wrapper around it. The plugin host (typically part of a DAW) dynamically loads the library and calls the LADSPA entry point. WebbPutting these parts together, you get a function that looks roughly like this. #[no_mangle] pub extern "C" fn rust_function() { } Just as when using C code in your Rust project you now need to transform data from and to a form that the rest of the application will understand..

While this solution is rather elegant since all it requires is a small macro decorating the struct, I found the ergonomics go out the window when using more complicated fields.

Webb17 aug. 2016 · From The Rust Programming Language chapter on FFI (emphasis mine): Certain types are defined to not be null. This includes references ( &T, &mut T ), boxes ( Box ), and function pointers ( extern "abi" fn () ). When interfacing with C, pointers that might be null are often used.

Webb与 function item types 不同（function item types 不可命名，Rust 编译器打印为 fn () -> i32 {bar} ，函数名 bar 包含在 {} 中），function pointer types 使用 fn 关键字进行命名（表示为 fn () -> i32 ），指向函数的入口地址（refer to a function whose identity is not necessarily known at compile-time），可以经由 function items 和 non-capturing closures 转换得到。 WebbMost foreign code exposes a C ABI, and Rust uses the platform's C calling convention by default when calling foreign functions.
