ValuesView
public struct ValuesView[K, V] where K: Hashable { /* private fields */ }Lazy Iterable view over the values of a dictionary.
Returned by Dictionary.values. Constructing the view is O(1) —
it stores the bucket pointer and capacity. The view is invalidated
by any mutation that may reallocate.
Examples
let dict = ["a": 1, "b": 2];
for v in dict.values { print(v) }
let sum = dict.values.iter().sum();
Representation
(buckets, capacity) — a pointer into the source dictionary's
bucket array plus the total slot count.
Memory Model
Value type that borrows the source dictionary's buffer.
Initializers
init(buckets: Pointer[Bucket[K, V]], capacity: Int64)
init(buckets: Pointer[Bucket[K, V]], capacity: Int64)Internal — constructs a view from a bucket pointer and capacity.
Use Dictionary.values to obtain a view.

type Item = VIterable element type — V.
type TargetIterator = ValuesIterator[K, V]
type TargetIterator = ValuesIterator[K, V]Concrete iterator type returned by iter().
Methods
public func iter() -> ValuesIterator[K, V]
public func iter() -> ValuesIterator[K, V]Returns a fresh ValuesIterator[K, V] over the view.
Each call returns a new iterator starting at the beginning of the bucket array.
