LeafData

LeafData is a “pseudo-protocol” wrapping the physically storable Swift data types Leaf can use directly

struct LeafData

Overview

(Bool, Int, Double, String, Array, Dictionary, Data) are the inherent root types supported, all of which may also be representable as Optional values.
NaturalType presents these cases plus Void as a case for functional LeafSymbols
nil is creatable, but only within context of a root base type - eg, .nil(.bool) == Bool?

static func == (LeafData, LeafData) -> Bool
Returns a Boolean value indicating whether two values are equal.

init(any LeafDataRepresentable)
init(arrayLiteral: LeafData...)
Creates an instance initialized with the given elements.
init(booleanLiteral: BooleanLiteralType)
Creates an instance initialized to the given Boolean value.
init(dictionaryLiteral: (String, LeafData)...)
Creates an instance initialized with the given key-value pairs.
init(floatLiteral: FloatLiteralType)
Creates an instance initialized to the specified floating-point value.
init(integerLiteral: IntegerLiteralType)
Creates an instance initialized to the specified integer value.
init(nilLiteral: ())
Creates an instance initialized with nil.
init(stringLiteral: StringLiteralType)
Creates an instance initialized to the given string value.

var array: [LeafData]?
Attempts to convert to [LeafData] or returns nil.
var bool: Bool?
Attempts to convert to Bool or returns nil.
var celf: LeafData.NaturalType
The case-self identity
var data: Data?
Attempts to convert to Data or returns nil.
var description: String
A textual representation of this instance.
var dictionary: [String : LeafData]?
Attempts to convert to [String: LeafData] or returns nil.
var double: Double?
Attempts to convert to Double or returns nil.
var hasUniformType: Bool?
Returns true if the object has a single uniform type
var int: Int?
Attempts to convert to Int or returns nil.
var isCollection: Bool
Returns true if the data can hold other data - we don’t consider Optional for this purpose
var isNil: Bool
Returns true if the data is nil or void.
var short: String
var string: String?
Attempts to convert to String or returns nil.
var uniformType: LeafData.NaturalType?
Returns the uniform type of the object, or nil if it is a non-uniform container

static var trueNil: LeafData
For convenience, trueNil is stored as .optional(nil, .void)

static func array([LeafData]?) -> LeafData
Creates a new LeafData from [LeafData].
static func bool(Bool?) -> LeafData
Creates a new LeafData from a Bool.
static func data(Data?) -> LeafData
Creates a new LeafData from Data.
static func dictionary([String : LeafData]?) -> LeafData
Creates a new LeafData from [String: LeafData].
static func double(Double?) -> LeafData
Creates a new LeafData from a Double.
static func int(Int?) -> LeafData
Creates a new LeafData from am Int.
static func `nil`(LeafData.NaturalType) -> LeafData
Creates a new LeafData for Optional<LeafData>
static func string(String?) -> LeafData
Creates a new LeafData from a String.
