I have an application where a long-lived "loader" thread takes
messages to load data, loads that data, and then sends it back to
the main thread via the standard concurrency primitives.
Something like this:
void threadFunc(Tid ownerTid)
{
while(true)
{
receive(
(int id, string path) { LoadThingByPath(ownerTid, id,
path); }
);
}
}
void LoadThingByPath(Tid ownerTid, int id, string path)
{
ret thing = MakeThing(path)
send(ownerTid, id, thing);
}
I know I need to make thing shared, but I don't know how do it
properly in this context. Casting to shared in send() works, but
then I have to accept a shared Thing on the other side, process
it as a shared Thing, etc. cast(Thing) doesn't appear to cast
away the shared qualifier either. Does that mean ALL of the
loaded data in my application needs to be shared all the time?
Is there not simply a way to transfer ownership?
