Last year, Lennart Poettering of the systemd fame, gave a presentation 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 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.
It 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, 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.
