Im learning zig for kernel bypass packet work. Aside from some noise, and one bug filed on cross compliation (prob simple to fix) bug, it works like I expect. Export of zig code to clib works fine. Comptime is great. Compile time superb. Like TB I will import no other modules ... and avoid all async.

But this link has got me concerned. When I get more ibverbs work done ill see how good/bad it is in rust.

In this kind of extremely low latency high throughput work there is hardly any (mostly none) MT data structures. Memory is pre-allocated for one pinned thread. Atomics are not much used either. So rust isn't going to help on design much. But I think rust/c interoperability is worse than zig.

In fairness to zig many of these issues were closed when zig 0.16.0 was released, which is what im using.

We'll see
