Enum DeferredNotify 

pub enum DeferredNotify {
    Put(DeferredNotifyPut),
    Process {
        completion: Sender<()>,
    },
}

One entry of C precord->ppnr->restartList — a whole processNotify waiting for the record, not just a put.

C queues the request (ellSafeAdd(&restartList, &ppn->restartNode), dbNotify.c:217) and restartCheck re-enters processNotifyCommon, which dispatches on ppn->requestType. A queue that could hold only a field-and-value put left the other request type — C processGetRequest, the port’s crate::server::database::PvDatabase::process_record_with_notify — with nowhere to wait, so its entry refused instead of queueing.

Variants

Put(DeferredNotifyPut)

C putProcessRequest / putProcessGetRequest: write the field, then process; the callback fires on the replayed cycle.

Process

C processGetRequest: process the record, write nothing.

Fields

completion: Sender<()>

The client’s completion channel, armed on the replayed process.
