Enum intmap::Entry

source · [−]

pub enum Entry<'a, V: 'a> {
    Occupied(OccupiedEntry<'a, V>),
    Vacant(VacantEntry<'a, V>),
}

Expand description

A view into a single entry in a IntMap, which may either be vacant or occupied.

The entry can be constructed by calling IntMap::entry with a key. It allows inspection and in-place manipulation of its value without repeated lookups.

Variants

`Occupied(OccupiedEntry<'a, V>)`

The entry is occupied.

`Vacant(VacantEntry<'a, V>)`

The entry is vacant.
