Struct OccupiedEntry

pub struct OccupiedEntry<'a, C: ?Sized> { /* private fields */ }

Implementations

impl<'a, C: 'a + Entriable> OccupiedEntry<'a, C>

pub fn key(&self) -> &usize

Gets a reference to the index of the entry.

pub fn remove_entry(self) -> (usize, C::T)

Take the ownership of the index and value from the container.

pub fn get(&self) -> &C::T

Gets a reference to the value in the entry.

pub fn get_mut(&mut self) -> &mut C::T

Gets a mutable reference to the value in the entry.

If you need a reference to the OccupiedEntry which may outlive the destruction of the Entry value, see into_mut.

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

Converts the OccupiedEntry into a mutable reference to the value in the entry with a lifetime bound to the map itself.

If you need multiple references to the OccupiedEntry, see get_mut.

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

Sets the value of the entry, and returns the entry’s old value.

pub fn remove(self) -> C::T

Takes the value out of the entry, and returns it. Keeps the allocated memory for reuse.

pub fn replace_entry(self, value: C::T) -> (usize, C::T)

Replaces the entry, returning the index and value.

pub fn replace_entry_with<F, R>(self, f: F) -> (Entry<'a, C>, R)

where F: FnOnce(&usize, C::T) -> (Option<C::T>, R),

Provides shared access to the key and owned access to the value of the entry and allows to replace or remove it based on the value of the returned option.
