No, the parent does not know about such a termination. These are the
following options that I know of:
1) The exceptions can be caught by the child and sent to the owner
explicitly as a special message that both understand.
Or the exception can directly be passed as a message:
2)
try {
// ...
} catch (shared(Exception) exc) {
owner.send(exc);
},
The owner receives that message just like a message:
receive(
// ...
(shared(Exception) exc) {
throw exc;
});
The code above re-throws the child's exception in the owner's context
but it could do anything else as well.
There are also the following exceptions that are related to std.concurrency:
* MessageMismatch
* OwnerTerminated
* LinkTerminated
* MailboxFull
* PriorityMessageException
I have some examples here:
