Implementations§

Source §

impl<'a, K, V> OccupiedEntry<'a, K, V>
where K: PrimInt, V: PartialEq,

Source

pub fn key(&self) -> K

Returns this entry’s key.

§Example

let mut mule_map = mule_map::MuleMap::<u32, usize, fnv_rs::FnvBuildHasher>::new();
mule_map.entry(5).or_insert(12);
assert_eq!(mule_map.entry(5).key(), 5);

Analogous to std::collections::hash_map::OccupiedEntry::key

Source

pub fn remove_entry(self) -> (K, V)
where V: Clone,

Take the ownership of the key and value from the map.

§Example

let mut mule_map = mule_map::MuleMap::<u32, usize, fnv_rs::FnvBuildHasher>::new();
mule_map.entry(5).or_insert(12);
if let mule_map::Entry::Occupied(o) = mule_map.entry(5) {
   o.remove_entry();
}

assert_eq!(mule_map.contains_key(5), false);

Analogous to std::collections::hash_map::OccupiedEntry::remove_entry

Source

pub fn get(&self) -> &V

Gets a reference to the value in the entry.

§Example

let mut mule_map = mule_map::MuleMap::<u32, usize, fnv_rs::FnvBuildHasher>::new();
mule_map.entry(5).or_insert(12);
if let mule_map::Entry::Occupied(o) = mule_map.entry(5) {
   assert_eq!(o.get(), &12);
}

Analogous to std::collections::hash_map::OccupiedEntry::get

Source

pub fn get_mut(&mut self) -> &mut V

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 OccupiedEntry::into_mut.

§Example

let mut mule_map = mule_map::MuleMap::<u32, usize, fnv_rs::FnvBuildHasher>::new();
mule_map.entry(5).or_insert(12);
if let mule_map::Entry::Occupied(mut o) = mule_map.entry(5) {
    *o.get_mut() += 10;
    assert_eq!(o.get(), &22);
    *o.get_mut() += 2;
}
assert_eq!(mule_map.get(5), Some(&24));

Analogous to std::collections::hash_map::OccupiedEntry::get_mut

Source

pub fn into_mut(self) -> &'a mut V

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 OccupiedEntry::get_mut.

§Example

let mut mule_map = mule_map::MuleMap::<u32, usize, fnv_rs::FnvBuildHasher>::new();
mule_map.entry(5).or_insert(12);
if let mule_map::Entry::Occupied(mut o) = mule_map.entry(5) {
    *o.into_mut() += 10;
}
assert_eq!(mule_map.get(5), Some(&22));

Analogous to std::collections::hash_map::OccupiedEntry::into_mut

Source

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

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

§Example

let mut mule_map = mule_map::MuleMap::<u32, usize, fnv_rs::FnvBuildHasher>::new();
mule_map.entry(5).or_insert(12);
if let mule_map::Entry::Occupied(mut o) = mule_map.entry(5) {
    assert_eq!(o.insert(15), 12);
}
assert_eq!(mule_map.get(5), Some(&15));

Analogous to std::collections::hash_map::OccupiedEntry::insert

Source

pub fn remove(self) -> V
where V: Clone,

Takes the value out of the entry, and returns it.

§Example

let mut mule_map = mule_map::MuleMap::<u32, usize, fnv_rs::FnvBuildHasher>::new();
mule_map.entry(5).or_insert(12);
if let mule_map::Entry::Occupied(mut o) = mule_map.entry(5) {
    assert_eq!(o.remove(), 12);
}
assert_eq!(mule_map.contains_key(5), false);
