Zig 0.16 introduces std.Io, a cross-platform I/O and concurrency interface, marking a significant step for the ecosystem. While the initial implementation uses a thread pool (std.Io.Threaded), the article highlights its limitations with high concurrency and mentions the upcoming std.Io.Evented for more efficient async I/O using io_uring and kqueue. The author also notes the release of zio 0.11, a third-party implementation using stackful coroutines and async OS APIs.
Background
Zig is a general-purpose programming language designed for robustness, optimality, and clarity. Asynchronous I/O is crucial for building scalable network applications, allowing efficient handling of many concurrent connections without the overhead of OS threads.
