How to do Vec<String>?
#2843
-
|
Dear cbindgen community, I am learning FFI/Rust and I am learning cbindgen, my goal is to optimize my Rust code in order to create the right header file. For instance this is how I currently define my Rust/C structs to pass the pointer to a Vec and its length #[repr(C)]
#[derive(Debug)]
pub struct MyStruct3 {
data: *const *const c_char,
length: c_int,
}And here is how I am converting from Rust to C let c_string_vec = unsafe {
let string_vec_data = (*c_data).data;
let string_vec_length = c_data.length;
std::slice::from_raw_parts(string_vec_data, string_vec_length as usize)
.iter()
.map(|&cstr| CStr::from_ptr(cstr).to_string_lossy().into_owned())
.collect::<Vec<String>>()
};I would like to ask, if there is a better way/more idiomatic way to do this from cbindgen perspective? thank you very much |
