A Rust implementation of the Socket.IO client protocol supporting both synchronous and asynchronous operations.
Rust-socketio is a Socket.IO client library written in Rust that enables real-time bidirectional communication with Socket.IO servers. It implements revision 5 of the Socket.IO protocol and revision 4 of the Engine.IO protocol, providing reliable real-time features for Rust applications. The library supports both synchronous and asynchronous operations with a clean, idiomatic API.
Rust developers building applications that require real-time communication with Socket.IO servers, such as chat applications, live dashboards, or collaborative tools. It's suitable for those who need protocol-compliant client functionality in Rust environments.
Developers choose Rust-socketio for its full protocol compliance, robust transport handling with automatic WebSocket upgrade and HTTP long-polling fallback, and support for both JSON and binary payloads. Its optional asynchronous runtime support using Tokio provides flexibility for non-blocking operations while leveraging Rust's safety and performance.

Implements all features of Socket.IO protocol revision 5, including custom events, acknowledgments, and binary data, ensuring reliable communication with compliant servers.
Automatically upgrades to WebSockets when available and falls back to HTTP long-polling, providing resilience in varying network conditions as per protocol specs.
Supports callbacks for standard events (open, close, error) and custom events, enabling easy integration with event-driven architectures using a clean API.
Uses serde_json for safe JSON handling and supports binary payloads, catering to diverse real-time data transmission needs with acknowledgment capabilities.
The asynchronous version is explicitly marked as experimental in the README, with interfaces subject to change, making it risky for production use without careful testing.
Each client can only connect to one namespace at a time, requiring multiple socket instances for multi-namespace applications, which adds complexity and resource overhead.
Requires servers to use at least Engine.IO protocol revision 4, limiting compatibility with older Socket.IO server implementations and potentially causing connection issues.
