Trait OccupiedEntry

pub trait OccupiedEntry<'a, T: ?Sized + GetEntry<'a>> {
    // Required methods
    fn key(&self) -> &T::Key;
    fn get(&self) -> &T::Value;
    fn get_mut(&mut self) -> &mut T::Value;
    fn insert(&mut self, value: T::Value) -> T::Value;
    fn into_mut(self) -> &'a mut T::Value;
    fn remove_entry(self) -> (T::Key, T::Value);
}

A trait for an entry with a value.

Required Methods

fn key(&self) -> &T::Key

Gets a reference to the key at this entry.

fn get(&self) -> &T::Value

Gets a reference to the value at this entry.

fn get_mut(&mut self) -> &mut T::Value

Gets a mutable reference to the value at this entry.

fn insert(&mut self, value: T::Value) -> T::Value

Inserts the given value into this entry, returning the old value.

fn into_mut(self) -> &'a mut T::Value

Consumes this entry handle, yielding a mutable reference to its value.

fn remove_entry(self) -> (T::Key, T::Value)

Removes this entry, returning both its key and value.
