Error handling 🤷‍♂️

src/main.rs

 
 fn main() {
     let cwd = env::current_dir().expect("Couldn't read current directory");
+
+    match fs::create_dir(cwd.join("public")) {
+        Ok(_) => {},
+        Err(err) => {
+            match err.kind() {
+                std::io::ErrorKind::AlreadyExists => {},
+                _ => panic!(err)
+            }
+        }
+    }
+
     let layout = fs::read_to_string(&cwd.join("templates").join("layout.html"))
         .expect("Couldn't find layout template");
     let post_paths = read_posts_dir(&cwd.join("posts"));
