[QUESTION]: Differentiate between TTL and cost based eviction

[George-Stroe]

Question.

Is there a way to differentiate between TTL and cost based evictions? The &Item returned from the onEvict callback has only the Key, Conflict, Value and Cost fields populated, making it impossible to identify what triggered the eviction.

If not, is there a plan for implementing this feature?
A possible solution would be to set the Item.Expiration when evicting the item, so that the cost based eviction would still have some time left.
