Function handle_async_components

pub(crate) fn handle_async_components(
    commands: Commands<'_, '_>,
    query: Query<'_, '_, (Entity, &mut AsyncComponent)>,
)

Polls each AsyncComponent in the ECS tree and checks for progress and/or completion.

If an AsyncComponent’s Receiver contains updates, they are appended to the current world. The AsyncComponent::task is polled for completion, and once completed the component is removed from the world.
