PriceLevel
enum PriceLevel
extension PriceLevel : CaseIterable, Equatable, Hashable, Identifiable
The price level of a place.
-
Returns a Boolean value indicating whether two values are equal.
Equality is the inverse of inequality. For any values
a
andb
,a == b
implies thata != b
isfalse
.Declaration
Swift
static func == (a: PriceLevel, b: PriceLevel) -> Bool
-
A type that can represent a collection of all values of this type.
Declaration
Swift
typealias AllCases = [PriceLevel]
-
A type representing the stable identity of the entity associated with an instance.
Declaration
Swift
typealias ID = PriceLevel
-
A collection of all values of this type.
Declaration
Swift
static var allCases: [PriceLevel] { get }
-
Place provides expensive services.
Declaration
Swift
case expensive
-
Place provides free services.
Declaration
Swift
case free
-
Hashes the essential components of this value by feeding them into the given hasher.
Implement this method to conform to the
Hashable
protocol. The components used for hashing must be the same as the components compared in your type’s==
operator implementation. Callhasher.combine(_:)
with each of these components.Important
In your implementation of
hash(into:)
, don’t callfinalize()
on thehasher
instance provided, or replace it with a different instance. Doing so may become a compile-time error in the future.Declaration
Swift
func hash(into hasher: inout Hasher)
-
The hash value.
Hash values are not guaranteed to be equal across different executions of your program. Do not save hash values to use during a future execution.
Important
hashValue
is deprecated as aHashable
requirement. To conform toHashable
, implement thehash(into:)
requirement instead. The compiler provides an implementation forhashValue
for you.Declaration
Swift
var hashValue: Int { get }
-
The stable identity of the entity associated with this instance.
Declaration
Swift
var id: PriceLevel { get }
-
Place provides inexpensive services.
Declaration
Swift
case inexpensive
-
Place provides moderately priced services.
Declaration
Swift
case moderate
-
Place price level is unspecified or unknown.
Declaration
Swift
case unspecified
-
Place provides very expensive services.
Declaration
Swift
case veryExpensive
