Struct std::collections::hash_map::OccupiedError [−][src]
The error returned by try_insert
when the key already exists.
Contains the occupied entry, and the value that was not inserted.
Fields
entry: OccupiedEntry<'a, K, V>
The entry in the map that was already occupied.
value: V
The value which was not inserted, because the entry was already occupied.
