sourcepub fn and_modify(self, f: impl FnOnce(&mut V)) -> Self
pub fn and_modify(self, f: impl FnOnce(&mut V)) -> Self
Apply a function to the stored value if it exists.
sourcepub fn or_default(self) -> RefMut<'a, K, V, S> where
V: Default,
pub fn or_default(self) -> RefMut<'a, K, V, S> where
V: Default,
Return a mutable reference to the element if it exists, otherwise insert the default and return a mutable reference to that.
sourcepub fn or_insert(self, value: V) -> RefMut<'a, K, V, S>
pub fn or_insert(self, value: V) -> RefMut<'a, K, V, S>
Return a mutable reference to the element if it exists, otherwise a provided value and return a mutable reference to that.
sourcepub fn or_insert_with(self, value: impl FnOnce() -> V) -> RefMut<'a, K, V, S>
pub fn or_insert_with(self, value: impl FnOnce() -> V) -> RefMut<'a, K, V, S>
Return a mutable reference to the element if it exists, otherwise insert the result of a provided function and return a mutable reference to that.

self,
value: impl FnOnce() -> Result<V, E>
