AnyField 

struct AnyField
 
extension AnyField : Equatable, Field, Hashable, RawRepresentable, Sendable

A type-erased Field.

  • Undocumented

    Declaration

    Swift

    init<T>(erasing field: T) where T : Field

  • Creates a type-erased UnknownField with the given raw value.

    Declaration

    Swift

    init(rawValue: UInt32)

  • id

    The number identifying the attribute in the trait, or the field in a Command, Event, etc.

    Declaration

    Swift

    var id: UInt32 { get }

  • The type of the field.

    Declaration

    Swift

    var type: FieldType { get }

  • The corresponding value of the raw type.

    A new instance initialized with rawValue will be equivalent to this instance. For example:

    enum PaperSize: String {
    case A4, A5, Letter, Legal
}

let selectedSize = PaperSize.Letter
print(selectedSize.rawValue)
// Prints "Letter"

print(selectedSize == PaperSize(rawValue: selectedSize.rawValue)!)
// Prints "true"

    Declaration

    Swift

    var rawValue: UInt32 { get }

  • Casts the field to the given type.

    Declaration

    Swift

    func cast<T>(_ type: T.Type = T.self) -> T? where T : Field

  • Returns true if the field is of the given type.

    Declaration

    Swift

    func `is`<T>(_ type: T.Type = T.self) -> Bool where T : Field

  • Returns true if the field is equal to the other field.

    Declaration

    Swift

    func isEqual(to other: any Field) -> 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.

    Declaration

    Swift

    static func == (lhs: AnyField, rhs: AnyField) -> Bool

    Parameters

    lhs

    A value to compare.
    rhs

    Another value to compare.
