High-frequency trading systems require ultra-low latency network stacks to minimize kernel overhead and system call context switches. The io_uring interface addresses this by utilizing shared memory ring buffers for asynchronous I/O submission and completion. This problem simulates a userspace implementation of such an asynchronous engine to manage non-blocking network events efficiently. Task Build a userspace simulation of an asynchronous network engine based on the io_uring architecture. Imp
