cppcoro is a C++ coroutine library and concurrency toolkit providing primitives for asynchronous tasks, lazy generators, and non-blocking execution. It functions as an asynchronous I/O framework for managing network sockets and file operations through an event loop.
The library features a work-stealing thread pool for distributing tasks across multiple cores and a set of async generators for producing lazy sequences of values both synchronously and asynchronously. It includes a concurrency toolkit with async mutexes, latches, and shared tasks to coordinate multi-threaded execution.
Its capability surface covers asynchronous control flow, including task definition, result transformation, and concurrent result aggregation. It provides execution context management to control where coroutines start and resume, alongside non-blocking file and network I/O support.
The project includes configuration utilities for managing build toolchains, compiler paths, and installation prefixes.
