I am currently learning Rust by making a dummy ECS, given the following function:

pub fn add_component<T: Component + 'static>(&mut self, component: T) {
        let type_id = TypeId::of::<T>(); 
}

I won’t compile without 'static –
I don’t understand why, since I am taking ownership of component – why is Rust worried about this component getting de-allocated.

the parameter type `T` may not live long enough
the parameter type `T` must be valid for the static lifetime

As long as it exists within the function scope (which it does) it should be good.

EDIT:

Component is defined as:

trait Component {
    fn update(&self);

    fn render(&self);
}
