One way to inteact with libqaul is via the
libqaul-ipc crate which
implements the same API as libqaul, while tunneling all calls through
a previously negotiated unix socket, using the cap'n proto IPC
The same ffi C interface as for libqaul can be used, meaning that it's possible to write a service that uses this high-performance IPC channel from nearly any language.
More docs to follow, as this is still WIP!
