Here are the data structures with brief descriptions:

[detail level 123]

Cuel_application_t	Top-level container for µEvLoop'd application
Cuel_autopool_t	Automatic pools are wrappers to object pools. They manage the acquisition and release cycle from objects issued at the pool by wrapping them in automatic pointers
Cuel_autoptr	Automatic pointers are pointers wrapped by information of where they were issued
Cuel_closure_t	Defines a closure, a tuple <function, context, destructor>
Cuel_conditional_t	Conditionals are constructs that provide functional flow control
Cuel_cqueue_t	Defines a circular queue of void pointers
▼Cuel_event_t	Events are special messages passed around the core. They represent tasks to be run at some point by the system
▼Cuel_event_detail
Cuel_event_listener	Contains the context of a particular signal listener
Cuel_event_observer	Contains the reference to an observer variable
Cuel_event_signal	Contains information related to an emitted `signal`
Cuel_event_timer	Contains information suitable for scheduling an event at the scheduler
Cuel_evloop_t	The event loop object
Cuel_func_mapper_t	Maps elements of an iterator to an area of memory. Each element is assigned to a `void` pointer slot
Cuel_iterator_array_t	A specialised iterator suitable for iterating over arrays of arbitrary data
Cuel_iterator_t	Iterators are data structures that wrap arbitrary collections of data and define ways of enumerating them
Cuel_llist_node_t	Defines a node of the linked list. Holds a void pointer
Cuel_llist_t	Defines a linked list. If it is empty, head == tail == NULL. Pushing or popping from both the head or tail is always O(1)
Cuel_module_t	A module is an isolated unit of behaviour with lifecycle hooks
Cuel_objpool_t	Pre-allocated memory bound to speciffic types suitable for providing dynamic object management in the stack
Cuel_pipeline_t	A pipeline is an ordered closure list to be run in sequence
Cuel_promise_segment_t	Defines a single synchronous operation to be invoked when the promise is either resolved or rejected
Cuel_promise_store_t	An issuer of promises. Contains references to pools for promises and segments
Cuel_promise_t	A promise is association of an asynchronous operation to the possible execution paths that follow its resolution. It is also a holder for the value it was settled with
Cuel_scheduer_t	The scheduler object
Cuel_signal_relay_t	Contains a signal vector and operates on in
Cuel_syspools_t	A container for the system pools
Cuel_sysqueues_t	A container for the system's internal queues
