I maintain a Rust binding to the AF_XDP parts of libbpf [1][2]. On the chance that more significant changes can be entertained in the switch to libxdp... The fact that many required functions like the ring access functions exist only in xsk.h makes building a binding more difficult because we need to wrap it with an extra C function [3]. From that perspective, it would be great if those could move to xsk.c.
