Nyx Native Runtime Engine
Deep dive into the architecture of the Nyx native runtime: memory arenas, cooperative green threads, async event loop, and specialized domain engines.
1. Runtime Subsystem Architecture
The Nyx runtime is a lightweight, zero-dependency C99/Native foundation linked directly into compiled Nyx executables:

3. Zero-Allocation Cooperative Event Loop
Nyx tasks run as stackless coroutines. When an async operation blocks on network I/O or disk, the runtime suspends the state machine and yields control back to the worker thread:
// Pseudocode of worker thread loop
void rt_worker_loop(rt_worker_t* worker) {
while (worker->running) {
rt_task_t* task = rt_deque_pop_bottom(&worker->local_queue);
if (!task) {
task = rt_steal_from_peers(worker);
}
if (task) {
task->poll_fn(task->context);
} else {
rt_epoll_wait_for_io(&worker->poller, 10 /* ms */);
}
}
}
