Struct OccupiedError

#[non_exhaustive]
pub struct OccupiedError<'a, K: 'a, V: 'a, A: Allocator = Global> { pub entry: OccupiedEntry<'a, K, V, A>, pub key: K, pub value: V }

The error returned by try_insert when the key already exists.

Contains the occupied entry, key, and the value that was not inserted.

Fields

entry: OccupiedEntry<'a, K, V, A>

The entry in the map that was already occupied.

key: K

The key which was not inserted, because the entry was already occupied.

value: V

The value which was not inserted, because the entry was already occupied.
