Struct apecs::LazyWorld

pub struct LazyWorld { /* private fields */ }

A resource used to gain safe access to the entire world.

LazyWorld exists in the world automatically and should be fetched as Read<LazyWorld, NoDefault>.

This is used primarily from syncronous systems to spawn async actions but can also be used to alter anything inside the world.

Modifications made to the world through this resource are applied in World::tick_lazy.
