## What it is
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

## Facets
- artifact type: library
- maturity: active
- function: message-queue, rpc, middleware, concurrency
- domain: microservices, developer-tools, robotics
- platform: windows, rust, cross-platform, embedded
- tags: zero-copy, shared-memory, lock-free, publish-subscribe, ipc, request-response, low-latency, service-oriented-architecture, real-time, linux, macos
