Implementations

impl<'a, K: Eq + Hash, V> Entry<'a, K, V>[src]

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

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

pub fn or_insert(self, value: V) -> &'a mut Vⓘ

Notable traits for &'_ mut I

impl<'_, I> Iterator for &'_ mut I where
    I: Iterator + ?Sized,  type Item = <I as Iterator>::Item;
[src]

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() -> V>(self, default: F) -> &'a mut Vⓘ

Notable traits for &'_ mut I

impl<'_, I> Iterator for &'_ mut I where
    I: Iterator + ?Sized,  type Item = <I as Iterator>::Item;
[src]

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.

pub fn key(&self) -> &Kⓘ

Notable traits for &'_ mut I

impl<'_, I> Iterator for &'_ mut I where
    I: Iterator + ?Sized,  type Item = <I as Iterator>::Item;
[src]

Returns a reference to this entry's key.

impl<'a, K: Eq + Hash, V: Default> Entry<'a, K, V>[src]

pub fn or_default(self) -> &'a mut Vⓘ

Notable traits for &'_ mut I

impl<'_, I> Iterator for &'_ mut I where
    I: Iterator + ?Sized,  type Item = <I as Iterator>::Item;
[src]

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.
