Enum Entry

impl<'a, K, V, S> Entry<'a, K, V, S>

fn or_insert(self: Self, default: V) -> &'a mut V

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

fn or_default(self: Self) -> &'a mut V
where
    V: Default

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.

fn or_insert_with<F: FnOnce() -> V>(self: Self, default: F) -> &'a mut 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.

fn and_modify<F>(self: Self, f: F) -> Self
where
    F: FnOnce(&mut V)

Provides in-place mutable access to an occupied entry before any potential inserts into the map.
