Given the following code:
pub trait Elements
where
Self: IntoWasmAbi,
{
fn get_pos(&self) -> Vec2<f64>;
fn get_pos_json(&self) -> String;
fn get_collision_bodies(&self) -> &HashMap<String, CollisionBody>;
fn add_collision_body(&mut self);
fn remove_collision_body(&mut self);
fn draw_collisions(&self, engine: &Engine);
}
#[wasm_bindgen]
pub struct Engine {
window_dimensions: Vec2<u32>,
speed: f64,
acceleration: f64,
elements: HashMap<String, Box<dyn Elements<Abi = String>>>,
context: CanvasRenderingContext2d,
}The current output is:
194 | pub trait Elements
| -------- this trait cannot be made into an object...
= help: consider turning `describe` into a method by giving it a `&self` argument or constraining it so it does not apply to trait objects
