Just realised my code isn’t cancel safe either. It is invalid if the user just drops a read future and the buffer itself while the operation is in the kernel.

It is just a PITA to get it fully right.

Probably need the buffer to come from the async library so user allocates the buffers using the async library like a sibling comment says.

It is just much easier to not use Rust and say futures should run fully always and can’t be just dropped and make some actual progress. So I’m just doing it in zig now
