Enum double_map::Entry

source · [−]

pub enum Entry<'a, K1: 'a, K2: 'a, V: 'a> {
    Occupied(OccupiedEntry<'a, K1, K2, V>),
    Vacant(VacantEntry<'a, K1, K2, V>),
}

Expand description

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

This enum is constructed from the entry method on DHashMap.

Variants

`Occupied(OccupiedEntry<'a, K1, K2, V>)`

An occupied entry.

`Vacant(VacantEntry<'a, K1, K2, V>)`

A vacant entry.
