Function should_apply_entity_update 

pub fn should_apply_entity_update(
    commands: &mut Commands<'_, '_>,
    partial_world: &mut PartialWorld,
    entity: Entity,
    entity_update_query: EntityUpdateQuery<'_, '_, '_>,
) -> bool

See RelativeEntityUpdate for details.

Calling this function will have the same effect as using the Command, but it’s more performant than the Command.
