It provides TCP, QUIC, and HTTP/3 networking capabilities with support for synchronous and asynchronous operations, making it suitable for a wide range of networking tasks including real-time multiplayer games. ## Features -- **TCP Networking**: Client and server implementations for TCP connections -- **HTTP Support**: Full HTTP client and server implementations with routing capabilities -- **QUIC Networking**: Encrypted, multi-stream transport via msquic — reliable streams for control plane, unreliable datagrams for low-latency state sync -- **Asynchronous Operations**: Thread pool-based async operations for improved performance -- **Cross-Platform**: Built for Unix-like systems with socket-based networking -- **Modern C++**: Uses C++ modules, STL containers, and modern C++ features +- **TCP Networking**: Client and server implementations for raw TCP connections. +- **QUIC Networking**: Encrypted, multi-stream transport via msquic — reliable streams for control plane, unreliable datagrams for low-latency state sync. +- **HTTP/3**: Client and server implementations on top of QUIC. Uses ALPN `h3`, QUIC bidi streams for requests/responses, the mandatory unidirectional control stream + SETTINGS frame (RFC 9114 §6.2.1), and a built-in QPACK codec (RFC 9204) with the full static table, Huffman *decoding* (RFC 7541), and literal-only emission. The QPACK dynamic table is unused; the optional QPACK encoder/decoder unidi streams are deliberately not opened (RFC 9204 §4.2 permits this when no dynamic-table operations are issued). The client is interoperable with mainstream public h3 endpoints (cloudflare, nghttp3-based servers, etc.). +- **Asynchronous Operations**: Thread pool–based async operations for improved performance. +- **Cross-Platform**: Built for Unix-like systems with socket-based networking. +- **Modern C++**: Uses C++20 modules, STL containers, and modern C++ features. ## Architecture @@ -23,12 +23,14 @@ The library follows a modular design using C++20 modules: - `Crafter.Network`: Main module that exports all components - `Crafter.Network:ClientTCP`: TCP client implementation - `Crafter.Network:ListenerTCP`: TCP server implementation -- `Crafter.Network:ClientHTTP`: HTTP client implementation -- `Crafter.Network:ListenerHTTP`: HTTP server implementation -- `Crafter.Network:HTTP`: HTTP protocol utilities and data structures +- `Crafter.Network:ClientHTTP`: HTTP/3 client (ALPN `h3`) +- `Crafter.Network:ListenerHTTP`: HTTP/3 server (ALPN `h3`) +- `Crafter.Network:HTTP`: HTTP request/response types and constructors - `Crafter.Network:ClientQUIC`: QUIC connection (client + accepted-server side) with reliable streams and unreliable datagrams - `Crafter.Network:ListenerQUIC`: QUIC listener accepting incoming connections +The `Crafter.Network:HTTP3` partition contains internal HTTP/3 wire-format helpers (QUIC varint, frame layer, QPACK static-table codec) and is intentionally not re-exported from the main module — it is shared between the `ClientHTTP` and `ListenerHTTP` implementations. + ## Components ### TCP Components @@ -53,30 +55,38 @@ Crafter::ListenerTCP listener(8080, callback); listener.ListenSyncSync(); // Synchronous listening ``` -### HTTP Components +### HTTP/3 Components + +HTTP/3 runs over QUIC, which always requires TLS.
