pub fn as_mut(

_: ModifyingPieces
) -> &mut DenseSlotMap<PieceId, GPiece>
Methods from Deref<Target = DenseSlotMap<PieceId, GPiece>>
sourcepub fn len(&self) -> usize
pub fn len(&self) -> usize
Returns the number of elements in the slot map.
Examples
let mut sm = DenseSlotMap::with_capacity(10);
sm.insert("len() counts actual elements, not capacity");
let key = sm.insert("removed elements don't count either");
sm.remove(key);
assert_eq!(sm.len(), 1);
sourcepub fn is_empty(&self) -> bool
pub fn is_empty(&self) -> bool
Returns if the slot map is empty.
Examples
let mut sm = DenseSlotMap::new();
let key = sm.insert("dummy");
assert_eq!(sm.is_empty(), false);
sm.remove(key);
assert_eq!(sm.is_empty(), true);
sourcepub fn capacity(&self) -> usize
pub fn capacity(&self) -> usize
Returns the number of elements the DenseSlotMap
can hold without
reallocating.
Examples
let sm: DenseSlotMap<_, f64> = DenseSlotMap::with_capacity(10);
assert_eq!(sm.capacity(), 10);
sourcepub fn contains_key(&self, key: K) -> bool
pub fn contains_key(&self, key: K) -> bool
sourcepub fn get(&self, key: K) -> Option<&V>
pub fn get(&self, key: K) -> Option<&V>
Returns a reference to the value corresponding to the key.
Examples
let mut sm = DenseSlotMap::new();
let key = sm.insert("bar");
assert_eq!(sm.get(key), Some(&"bar"));
sm.remove(key);
assert_eq!(sm.get(key), None);
sourcepub unsafe fn get_unchecked(&self, key: K) -> &V
pub unsafe fn get_unchecked(&self, key: K) -> &V
Returns a reference to the value corresponding to the key without version or bounds checking.
Safety
This should only be used if contains_key(key)
is true. Otherwise it is
potentially unsafe.
Examples
let mut sm = DenseSlotMap::new();
let key = sm.insert("bar");
assert_eq!(unsafe { sm.get_unchecked(key) }, &"bar");
sm.remove(key);
// sm.get_unchecked(key) is now dangerous!
sourcepub fn iter(&self) -> Iter<'_, K, V>ⓘNotable traits for Iter<'a, K, V>impl<'a, K, V> Iterator for Iter<'a, K, V> where
K: 'a + Key, type Item = (K, &'a V);
pub fn iter(&self) -> Iter<'_, K, V>ⓘNotable traits for Iter<'a, K, V>impl<'a, K, V> Iterator for Iter<'a, K, V> where
K: 'a + Key, type Item = (K, &'a V);
K: 'a + Key, type Item = (K, &'a V);
An iterator visiting all key-value pairs in arbitrary order. The
iterator element type is (K, &'a V)
.
Examples
let mut sm = DenseSlotMap::new();
let k0 = sm.insert(0);
let k1 = sm.insert(1);
let k2 = sm.insert(2);
let mut it = sm.iter();
for (k, v) in sm.iter() {
println!("key: {:?}, val: {}", k, v);
}
sourcepub fn keys(&self) -> Keys<'_, K, V>ⓘNotable traits for Keys<'a, K, V>impl<'a, K, V> Iterator for Keys<'a, K, V> where
K: 'a + Key, type Item = K;
pub fn keys(&self) -> Keys<'_, K, V>ⓘNotable traits for Keys<'a, K, V>impl<'a, K, V> Iterator for Keys<'a, K, V> where
K: 'a + Key, type Item = K;
K: 'a + Key, type Item = K;
An iterator visiting all keys in arbitrary order. The iterator element type is K.
Examples
let mut sm = DenseSlotMap::new();
let k0 = sm.insert(10);
let k1 = sm.insert(20);
let k2 = sm.insert(30);
let keys: HashSet<_> = sm.keys().collect();
let check: HashSet<_> = vec![k0, k1, k2].into_iter().collect();
assert_eq!(keys, check);
sourcepub fn values(&self) -> Values<'_, K, V>ⓘNotable traits for Values<'a, K, V>impl<'a, K, V> Iterator for Values<'a, K, V> where
K: 'a + Key, type Item = &'a V;
pub fn values(&self) -> Values<'_, K, V>ⓘNotable traits for Values<'a, K, V>impl<'a, K, V> Iterator for Values<'a, K, V> where
K: 'a + Key, type Item = &'a V;
K: 'a + Key, type Item = &'a V;
An iterator visiting all values in arbitrary order. The iterator element
type is &'a V
.
Examples
let mut sm = DenseSlotMap::new();
let k0 = sm.insert(10);
let k1 = sm.insert(20);
let k2 = sm.insert(30);
let values: HashSet<_> = sm.values().collect();
let check: HashSet<_> = vec![&10, &20, &30].into_iter().collect();
