main expect !void so i guess its fine

No

magic sail
#

does not make any difference, I still get the segfault 🥲

#

calling flush on socket writer causes a segfault

#

Got it

var writer_interface = conn_writer.interface;

has to be

var writer_interface = &conn_writer.interface;

I'm stupid 🙃

Interfaces have to be taken by value, not copied

magic sail

Yeah..
