{"guid":"ba519802-5565-51fe-abc6-db42bb831aff","title":"Forget zbus, zlink is the future of IPC in Rust","subtitle":null,"slug":"all-systems-go-2025-340-forget-zbus-zlink-is-the-future-of-ipc-in-rust","link":"https://cfp.all-systems-go.io/all-systems-go-2025/talk/SYGBNH/","description":"Last year, Lennart Poettering of the systemd fame, [gave a presentation](https://media.ccc.de/v/all-systems-go-2024-276-varlink-now-) at this very same conference, where he introduced Varlink, a modern yet simple IPC mechanism. He presented a case for Varlink, rather than [D-Bus](https://en.wikipedia.org/wiki/D-Bus) to be the future of Inter-process communication on Linux. As someone who works on D-Bus, I took upon myself to prove him wrong, only to find out that I achieved exactly the opposite.\n\nIt didn't take long before I got convinced of his vision. Since I was largely responsible for giving the world [an easy to use D-Bus Rust library](https://crates.io/crates/zbus), I thought it's only fitting that I do the same for Varlink. This talk will be the story of the creation of such a library, the challenges I faced, where Varlink fits the Rust idioms really well and where it does not and how all of this affected the development and the API.\n\nLicensed to the public under https://creativecommons.org/licenses/by/4.0/de/","original_language":"eng","persons":["Zeeshan Ali Khan"],"view_count":266,"promoted":false,"date":"2025-10-01T14:05:00.000+02:00","release_date":"2025-10-01T00:00:00.000+02:00","updated_at":"2026-04-21T13:00:04.859+02:00","tags":["340","2025","asg2025","Galerie","asg2025-eng","asg2025","Day 2"],"length":2294,"duration":2294,"thumb_url":"https://static.media.ccc.de/media/events/all_systems_go/2025/340-ba519802-5565-51fe-abc6-db42bb831aff.jpg","poster_url":"https://static.media.ccc.de/media/events/all_systems_go/2025/340-ba519802-5565-51fe-abc6-db42bb831aff_preview.jpg","timeline_url":"https://static.media.ccc.de/media/events/all_systems_go/2025/340-ba519802-5565-51fe-abc6-db42bb831aff.timeline.jpg","thumbnails_url":"https://static.media.ccc.de/media/events/all_systems_go/2025/340-ba519802-5565-51fe-abc6-db42bb831aff.thumbnails.vtt","frontend_link":"https://media.ccc.de/v/all-systems-go-2025-340-forget-zbus-zlink-is-the-future-of-ipc-in-rust","url":"https://api.media.ccc.de/public/events/ba519802-5565-51fe-abc6-db42bb831aff","conference_title":"All Systems Go!
