Enum `Entry`

enum Entry<'a, K, V>

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 Map.

Variants

Vacant(VacantEntry<'a, K, V>): A vacant Entry.
Occupied(OccupiedEntry<'a, K, V>): An occupied Entry.

Implementations

`impl<'a, K: Ord, V> Entry<'a, K, V>`

fn key(self: &Self) -> &K: Returns a reference to this entry's key.
fn or_insert(self: Self, default: V) -> &'a mut V: Ensures a value is in the entry by inserting the default if empty, and returns a mutable reference to the value in the entry.
fn or_insert_with<F>(self: Self, default: F) -> &'a mut V where F: FnOnce() -> V: 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.
