Implementations

impl<'a, K: Key, A: ?Sized + UnsafeAnyExt + 'a> Entry<'a, K, A>

pub fn or_insert(self, default: K::Value) -> &'a mut K::Value

where K::Value: Any + Implements<A>,

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() -> K::Value>( self, default: F, ) -> &'a mut K::Value

where K::Value: Any + Implements<A>,

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.
