Struct std::collections::btree_map::OccupiedError [−][src]
pub struct OccupiedError<'a, K, V> where
K: 'a,
V: 'a, { pub entry: OccupiedEntry<'a, K, V>, pub value: V, }
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.
