debugDescription
var debugDescription: String { get }
A textual representation of this instance, suitable for debugging.
Calling this property directly is discouraged. Instead, convert an
instance of any type to a string by using the String(reflecting:)
initializer. This initializer works with any type, and uses the custom
debugDescription property for types that conform to
CustomDebugStringConvertible:
struct Point: CustomDebugStringConvertible {
let x: Int, y: Int
var debugDescription: String {
return "(\(x), \(y))"
}
}
let p = Point(x: 21, y: 30)
let s = String(reflecting: p)
print(s)
// Prints "(21, 30)"
The conversion of p to a string in the assignment to s uses the
Point type's debugDescription property.
description
var description: String { get }
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 custom
description property for types that conform to
CustomStringConvertible:
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 p to a string in the assignment to s uses the
Point type's description property.
format(format:)
func format(format: NameFormat) -> String
Formats a name into a string based on the available output formats.
The default separator is .
hash(into:)
func hash(into hasher: inout Hasher)
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. Call hasher.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. -
Parameter hasher: The hasher to use when combining the components of this instance.
isSln()
func isSln() -> Bool
Returns whether this name is a second-level name (Ex. test.iota)
isSubname()
func isSubname() -> Bool
Returns whether this name is a subname (Ex. sub.test.iota)
label(index:)
func label(index: UInt32) -> String?
Get the label at the given index
labels()
func labels() -> [String]
Get all of the labels. NOTE: These are in reverse order starting with the top-level name and proceeding to subnames.
numLabels()
func numLabels() -> UInt32
Returns the number of labels including TLN.
parent()
func parent() -> Name?
parents; second-level names return None.
fromStr(s:)
static func fromStr(s: String) throws -> Name
!=(_:_:)
static func != (lhs: Self, rhs: Self) -> Bool
Returns a Boolean value indicating whether two values are not equal.
Inequality is the inverse of equality. For any values a and b, a != b
implies that a == b is false.
This is the default implementation of the not-equal-to operator (!=)
for any type that conforms to Equatable.
- Parameters:
- lhs: A value to compare.
- rhs: Another value to compare.
==(_:_:)
static func == (self: Name, other: Name) -> Bool
Returns a Boolean value indicating whether two values are equal.
Equality is the inverse of inequality. For any values a and b,
a == b implies that a != b is false.
- Parameters:
- lhs: A value to compare.
- rhs: Another value to compare.
