[$] One Sized trait does not fit all
In Rust, types either possess a constant size known at compile time, or a
dynamically calculated size known at
run time. That is fine for most purposes, but recent proposals for the language
have shown the need for a more fine-grained hierarchy.
RFC 3729 from David Wood and Rémy Rakic would add a hierarchy of
traits to describe types with sizes known under different circumstances. While
the idea has been subject … ⌘ Read more

New Rust-Based BUS1 In-Kernel IPC In Development For The Linux Kernel
After KDBUS failed to make it into the mainline Linux kernel more than one decade ago as an in-kernel version of D-Bus, BUS1 was proposed as a clean sheet design for in-kernel, capability-based inter-process communication (IPC). BUS1 didn’t gain enough traction to make it to the mainline kernel and then many of the same developers devised Dbus-Broker as a more performant D-Bus user-space implementation. Well, as a big surprise now, a new version of BUS1 … ⌘ Read more
