Enum vec_map::Entry[−][src]

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

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

Variants

Vacant(VacantEntry<'a, V>)

A vacant Entry

Occupied(OccupiedEntry<'a, V>)

An occupied Entry

Implementations

impl<'a, V> Entry<'a, V>[src]

pub fn or_insert(self, default: V) -> &'a mut V[src]

Ensures a value is in the entry by inserting the default if empty, and returns a mutable reference to the value in the entry.

pub fn or_insert_with<F: FnOnce() -> V>(self, default: F) -> &'a mut V[src]

Ensures a value is in the entry by inserting the result of the default function if empty, and returns a mutable reference to the value in the entry.
