source · [−]

pub struct OccupiedError<'a, K, V, S, A: Allocator + Clone = Global> {
    pub entry: OccupiedEntry<'a, K, V, S, A>,
    pub value: V,
}

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, S, A>

The entry in the map that was already occupied.

value: V

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