Use of library

For get the version as a pointer const c_char :

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

For get a json with all svg and position inside as a pointer const c_char: ``` /// language = 0 => English /// language = 1 => French

[no_mangle]

pub extern "C" fn compute( year: cint, month: cint, day: cint, hour: cint, min: cint, sec: cdouble, lat: cdouble, lng: cdouble, maxsize: cdouble, language: cint, path: *const cchar, ) -> *const cchar { let lang: Language = match FromPrimitive::fromi32(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 pathcstr = unsafe { CStr::fromptr(path) }; let pathstr: &str = pathcstr.tostr().unwrap(); let data = svgdraw::chart(maxsize as f32, d, &pathstr, lang); CString::new(serdejson::tostring(&data).unwrap()) .unwrap() .into_raw() }

```

For transit

```

/// language = 0 => English /// language = 1 => French

[no_mangle]

pub extern "C" fn computetransit( year: cint, month: cint, day: cint, hour: cint, min: cint, sec: cdouble, lat: cdouble, lng: cdouble, yeartransit: cint, monthtransit: cint, daytransit: cint, hourtransit: cint, mintransit: cint, sectransit: cdouble, lattransit: cdouble, lngtransit: cdouble, maxsize: cdouble, language: cint, path: *const cchar, ) -> *const cchar { let lang: Language = match FromPrimitive::fromi32(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 dt = DataChartNatal { year: yeartransit, month: monthtransit, day: daytransit, hour: hourtransit, min: mintransit, sec: sectransit as f32, lat: lattransit as f32, lng: lngtransit as f32, }; let pathcstr = unsafe { CStr::fromptr(path) }; let pathstr: &str = pathcstr.tostr().unwrap(); let data = svgdraw::chartwithtransit(maxsize as f32, d, dt, &pathstr, lang); CString::new(serdejson::tostring(&data).unwrap()) .unwrap() .intoraw() }

``` For all aspects (only major at this moment)

``` /// language = 0 => English /// language = 1 => French

[no_mangle]

pub extern "C" fn aspects(language: cint) -> *const cchar { let lang: Language = match FromPrimitive::fromi32(language as i32) { Some(Language::English) => Language::English, Some(Language::French) => Language::French, None => Language::English, }; let data = svgdraw::allaspects(lang); CString::new(serdejson::tostring(&data).unwrap()) .unwrap() .intoraw() } ```
