iceoryx2 is an ultra-low latency inter-process communication middleware with a Rust core, offering true zero-copy, lock-free messaging via shared memory. It supports publish/subscribe, request/response, event signaling, and blackboard patterns in a service-oriented architecture.

Use cases

• send large payloads between processes with zero-copy shared memory
• build low-latency pub/sub communication between applications
• implement request-response IPC between processes
• signal events between processes with minimal latency
• build robotics or automotive middleware with predictable latency
• share huge datasets between multiple processes efficiently

When to choose

• you need consistently low transmission latency regardless of payload size
• you want zero-copy, lock-free IPC on the same machine
• you need publish-subscribe or request-response patterns across processes
• you're building real-time systems like robotics or automotive software in Rust

When to avoid

• you need communication across a network rather than between local processes
• you want a high-level broker-based message queue like Kafka or RabbitMQ
• your project requires a mature 1.0 API - the library is still pre-1.0
• you need bindings for languages other than those officially supported
