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

Expand description

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, A>

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

The entry in the map that was already occupied.

value: V

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

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