StructureSwift5.9.0
Index
The position of a key-value pair in a dictionary.
@frozen struct IndexDictionary has two subscripting interfaces:
Subscripting with a key, yielding an optional value:
v = d[k]!Subscripting with an index, yielding a key-value pair:
(k, v) = d[i]

where Key:HashableConformances
protocol ComparableA type that can be compared using the relational operators
<,<=,>=, and>.protocol EquatableA type that can be compared for value equality.
protocol HashableA type that can be hashed into a
Hasherto produce an integer hash value.
Members
static func < (Dictionary<Key, Value>.Index, Dictionary<Key, Value>.Index) -> Bool static func == (Dictionary<Key, Value>.Index, Dictionary<Key, Value>.Index) -> Bool func hash(into: inout Hasher)
Features
static func != (Self, Self) -> Bool static func ... (Self) -> PartialRangeFrom<Self> Returns a partial range extending upward from a lower bound.
static func ... (Self) -> PartialRangeThrough<Self> Returns a partial range up to, and including, its upper bound.
static func ... (Self, Self) -> ClosedRange<Self> Returns a closed range that contains both of its bounds.
static func ..< (Self) -> PartialRangeUpTo<Self> Returns a partial range up to, but not including, its upper bound.
static func ..< (Self, Self) -> Range<Self> Returns a half-open range that contains its lower bound but not its upper bound.

where Key:Hashable, Key:Sendable, Value:SendableConformances
protocol SendableA type whose values can safely be passed across concurrency domains by copying.
