CMFormatDescription.EqualityMask

struct · iOS 13.0+ · SDK 27.1

struct EqualityMask

Mask bits passed to (and returned from) `equalTo(otherFormatDescription:equalityMask:)`, representing various parts of an audio format description.

streamBasicDescription

TypeScript

get streamBasicDescription(): CMFormatDescription_EqualityMask

Swift declaration

Represents the `AudioStreamBasicDescription`.

Represents the magic cookie.

channelLayout

TypeScript

get channelLayout(): CMFormatDescription_EqualityMask

Swift declaration

static let channelLayout: CMFormatDescription.EqualityMask

Represents the `AudioChannelLayout`.

all

TypeScript

get all(): CMFormatDescription_EqualityMask

Swift declaration

static let all: CMFormatDescription.EqualityMask

Represents all the parts of an audio format description.

init · iOS 13.0+

init

TypeScript

init(rawValue: number): CMFormatDescription_EqualityMask

Swift declaration

init(rawValue: CMAudioFormatDescriptionMask)

Creates a new option set from the given raw value. This initializer always succeeds, even if the value passed as `rawValue` exceeds the static properties declared as part of the option set. This example creates an instance of `ShippingOptions` with a raw value beyond the highest element, with a bit mask that effectively contains all the declared static members. let extraOptions = ShippingOptions(rawValue: 255) print(extraOptions.isStrictSuperset(of: .all)) // Prints "true" - Parameter rawValue: The raw value of the option set to create. Each bit of `rawValue` potentially represents an element of the option set, though raw values may include bits that are not defined as distinct values of the `OptionSet` type.

rawValue

TypeScript

getRawValue($self: CMFormatDescription_EqualityMask): number

Swift declaration

let rawValue: CMAudioFormatDescriptionMask

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"
