+- you will also need to import Box and async_trait for any struct implementing async trait to work otherwise you'll get a compile error
 
 ```rust
-use async_trait::async_trait;
-use alloc::{string::String, vec::Vec, boxed::Box};
-
 #[async_trait]
 pub trait Application {
-	fn new() -> Self;
+    fn new() -> Self;
-
+    async fn run(&mut self, _: Vec<String>) -> Result<(), Error> {
-	async fn run(&mut self, _: Vec<String>) -> Result<(), Error> {
+        Ok(())
-		Ok(())
+    }
-	}
 }
