A single portion of a trip from one location to another.
-
Returns a Boolean value indicating whether two values are equal.
Equality is the inverse of inequality. For any values
aandb,a == bimplies thata != bisfalse.Declaration
Swift
static func == ( lhs : Leg , rhs : Leg ) -> BoolParameters
lhsA value to compare.
rhsAnother value to compare.
-
A textual representation of this instance.
Calling this property directly is discouraged. Instead, convert an instance of any type to a string by using the
String(describing:)initializer. This initializer works with any type, and uses the customdescriptionproperty for types that conform toCustomStringConvertible:struct Point : CustomStringConvertible { let x : Int , y : Int var description : String { return "( \( x ) , \( y ) )" } } let p = Point ( x : 21 , y : 30 ) let s = String ( describing : p ) print ( s ) // Prints "(21, 30)"The conversion of
pto a string in the assignment tosuses thePointtype’sdescriptionproperty.Declaration
Swift
var description : String { get } -
The distance of this leg of the trip.
Declaration
Swift
var distanceMeters : UInt { get } -
The time it takes to finish this leg of the trip.
Declaration
Swift
var duration : TimeInterval { get } -
Hashes the essential components of this value by feeding them into the given hasher.
Implement this method to conform to the
Hashableprotocol. 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 thehasherinstance 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
hashValueis deprecated as aHashablerequirement. To conform toHashable, implement thehash(into:)requirement instead. The compiler provides an implementation forhashValuefor you.Declaration
Swift
var hashValue : Int { get }
