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, }
🔬 This is a nightly-only experimental API. (map_try_insert #82766)

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>
🔬 This is a nightly-only experimental API. (map_try_insert #82766)

The entry in the map that was already occupied.

value: V
🔬 This is a nightly-only experimental API. (map_try_insert #82766)

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