Julia is jit compiled by llvm to your native machine code. Correctly written Julia is within 1.5 the speed of C. It removes the complexity of needing to do the

  You make it sound like ffi is a nasty 3 letter word ;). It look me 3 lines of code to import the dll, assign the signature and call the function, I'd hardly call that complex.

    this is probably a dumb question but did you just compile the rust binary and then expose the functions? how? I don't remember but does rust face header files?
    • vvanders 9y ago
      Yup, just declare the function like so: #[no_mangle] pub unsafe extern "C" fn transform_pcm( data: *mut c_short, len: c_uint, ramp_time: c_uint, tone_delta_frame: c_float) { then call from python: gen_pcm_dll = ctypes.cdll.LoadLibrary("gen_pcm_rust/target/release/gen_pcm.dll") gen_pcm_dll.transform_pcm.argtypes = [ctypes.c_void_p, ctypes.c_uint, ctypes.c_uint, ctypes.c_float] gen_pcm_dll.transform_pcm(ptr, len(pcm), ramp_time, tone_delta_frame) Rust doesn't generate headers(although there are helper libs if you want) and you don't need them to FFI.
