Interfacing Rust with Xen

on YouTube ↗28m

" summary

Proof-of-concept Rust library issues raw Xen hypercalls (implemented the XEN HYPERCALL: console read case) and runs in both hosted and freestanding environments by splitting into no_std and std parts. A small CLI called XR exercises the flow; a generator in a GitLab repo converts a simple TOML spec into Rust structs and C headers (primitive and pointer types work; unions/complex types are WIP). Goal is a single Rust library replacing C dynamic+static layers with generated, mostly-safe FFI.
