Iceoryx2 – Fast IPC Library for Rust, C++, and C

In plain words

Iceoryx2 is an inter-process communication library for Rust, C++, and C that enables fast data exchange between processes. It offers circular buffers, message history, event notifications, and publish-subscribe messaging without requiring a central broker. The library is designed for applications like robotics that need to pass data such as camera frames across multiple processes efficiently and reliably, with features to handle memory management and ensure processes receive recent data upon connection.

From the sources

Announcing the release of iceoryx2 version 0.4.0, highlighting key features like daemon-less operation, improved performance, enhanced modularity, and C/C++ language bindings.

iceoryx2 is a service-based inter-process communication (IPC) library designed to make communication between processes as fast as possible - like Unix domain sockets or message queues, but orders of magnitude faster and easier to use. It also comes with advanced features such as circular buffers, history, event notifications, publish-subscribe messaging, and a decentralized architecture with no need for a broker. With today's iceoryx2 v0.4.0 release , we've achieved many of our milestones and are now close to feature parity with its predecessor, the trusty old iceoryx . With this new release, we're faster than ever. On some platforms, latency is even under 100ns ! Be sure to check out our…from ekxide.io

  Comprehensive inter-process communication (IPC) toolkit in modern C++2024 · github.com · ▲88

  If you work in C++, and you would like 2+ programs to share data structures (and/or native I/O handles a.k.a. FDs) among each other, there is a good chance Flow-IPC - will make it considerably less annoying to code than typical approaches; and - may massively reduce the latency involved. Those sharing Cap'n Proto-encoded data may have particular interest. Cap'n Proto (https://capnproto.org) is fantastic at its core task - in-place serialization with zero-copy - and we wanted to make the IPC (inter-process communication) involving capnp-serialized messages be zero-copy,…

  Whirlwind – Async concurrent hashmap for Rust2024 · github.com · ▲140

  Hey HN, this is Will and David from Fortress (https://news.ycombinator.com/item?id=41426998). We use a lot of async Rust internally, and created this library out of a need for an async-aware concurrent hashmap since there weren’t many available in the Rust ecosystem. Whirlwind is a sharded HashMap with a fully asynchronous API. Just as dashmap is a replacement for std::sync::RwLock, whirlwind aims to be a replacement for tokio::sync::RwLock. It has a similar design and performance characteristics to dashmap, but seems to perform better in read-heavy workloads with tokio's…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
