[−][src]Enum trie::map::Entry

pub enum Entry<'a, T: 'a> {
    Occupied(OccupiedEntry<'a, T>),
    Vacant(VacantEntry<'a, T>),
}

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

Variants

Occupied(OccupiedEntry<'a, T>)

An occupied entry.

Vacant(VacantEntry<'a, T>)

A vacant entry.

Implementations

impl<'a, T> Entry<'a, T>[src]

pub fn or_insert(self, default: T) -> &'a mut T[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() -> T>(self, default: F) -> &'a mut T[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.
