Function callback types.
Function prototype for creating an iterator from a poly.
Used to create iterators from poly objects with the iterable mixin. When a filter is provided, an array of two iterators must be passed to the function. This allows the mixin implementation to create a chained iterator when necessary, which requires two iterator objects.
- Parameters
-
| world | The world or stage for which to create the iterator. |
| iterable | An iterable poly object. |
| it | The iterator to create (out parameter) |
| filter | Optional term to filter results. |

| typedef void(* ecs_run_action_t) (ecs_iter_t *it) |
Function prototype for runnables (systems, observers).
The run callback overrides the default behavior for iterating through the results of a runnable object.
The default runnable iterates the iterator, and calls an iter_action (see below) for each returned result.
- Parameters
-
| it | The iterator to be iterated by the runnable. |
