Rust语言的经典占星术

由Stéphane Bressani创建的Rust库（[email protected]）

库的使用

获取版本作为指针const c_char

pub extern "C" fn sweversion() -> *const c_char {
    CString::new(handler_swe02::version()).unwrap().into_raw()
}

获取包含所有svg和位置的json作为指针const c_char

#[no_mangle]
pub extern "C" fn compute(
    year: c_int,
    month: c_int,
    day: c_int,
    hour: c_int,
    min: c_int,
    sec: c_double,
    lat: c_double,
    lng: c_double,
    max_size: c_double,
    language: c_int,
    path: *const c_char,
) -> *const c_char {
    let lang: Language = match FromPrimitive::from_i32(language as i32) {
        Some(Language::English) => Language::English,
        Some(Language::French) => Language::French,
        None => Language::English,
    };
    let d = DataChartNatal {
        year: year,
        month: month,
        day: day,
        hour: hour,
        min: min,
        sec: sec as f32,
        lat: lat as f32,
        lng: lng as f32,
    };
    let path_c_str = unsafe { CStr::from_ptr(path) };
    let path_str: &str = path_c_str.to_str().unwrap();
    let data = svg_draw::chart(max_size as f32, d, &path_str, lang);
    CString::new(serde_json::to_string(&data).unwrap())
        .unwrap()
        .into_raw()
}

用于天文转移

#[no_mangle]
pub extern "C" fn compute_transit(
    year: c_int,
    month: c_int,
    day: c_int,
    hour: c_int,
    min: c_int,
    sec: c_double,
    lat: c_double,
    lng: c_double,
    year_transit: c_int,
    month_transit: c_int,
    day_transit: c_int,
    hour_transit: c_int,
    min_transit: c_int,
    sec_transit: c_double,
    lat_transit: c_double,
    lng_transit: c_double,
    max_size: c_double,
    language: c_int,
    path: *const c_char,
) -> *const c_char {
    let lang: Language = match FromPrimitive::from_i32(language as i32) {
        Some(Language::English) => Language::English,
        Some(Language::French) => Language::French,
        None => Language::English,
    };
    let d = DataChartNatal {
        year: year,
        month: month,
        day: day,
        hour: hour,
        min: min,
        sec: sec as f32,
        lat: lat as f32,
        lng: lng as f32,
    };
    let d_t = DataChartNatal {
        year: year_transit,
        month: month_transit,
        day: day_transit,
        hour: hour_transit,
        min: min_transit,
        sec: sec_transit as f32,
        lat: lat_transit as f32,
        lng: lng_transit as f32,
    };
    let path_c_str = unsafe { CStr::from_ptr(path) };
    let path_str: &str = path_c_str.to_str().unwrap();
    let data =
        svg_draw::chart_with_transit(max_size as f32, d, d_t, &path_str, lang);
    CString::new(serde_json::to_string(&data).unwrap())
        .unwrap()
        .into_raw()
}

用于所有方面（目前只包括主要方面）

#[no_mangle]
pub extern "C" fn aspects(language: c_int) -> *const c_char {
    let lang: Language = match FromPrimitive::from_i32(language as i32) {
        Some(Language::English) => Language::English,
        Some(Language::French) => Language::French,
        None => Language::English,
    };
    let data = svg_draw::all_aspects(lang);
    CString::new(serde_json::to_string(&data).unwrap())
        .unwrap()
        .into_raw()
}
