pub struct RegisteredEventCache<T, Event: RegisterTaggedInternalEvent> { /* private fields */ }
Expand description
Metrics (eg. component_sent_event_bytes_total
) may need to emit tags based on
values contained within the events. These tags can’t be determined in advance.
Metrics need to be registered and the handle needs to be held onto in order to
prevent them from expiring and being dropped (this would result in the counter
resetting to zero).
CachedEvent
is used to maintain a store of these registered metrics. When a
new event is emitted for a previously unseen set of tags an event is registered
and stored in the cache.
