Description
I tried this to compile:
pub fn load(external_id: &String) -> Vec<u8> {
let map_store_path = construct_store_path(&MAPS_PATH.to_string(), external_id);
let map_path = construct_storable_path(&map_store_path, external_id);
let map_file = fs::File::open(&map_path);
let mut map_bytes = Vec::new();
try!(map_file.read_to_end(&map_bytes));
let map = json::decode(&map_bytes).unwrap();
vec![0]
}This is what happened:
