[src]
ⓘImportant traits for &'a mut R
pub fn or_insert(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.

F: FnOnce() -> V,
[src]
ⓘImportant traits for &'a mut R
pub fn or_insert_with<F>(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.
