struct Iteratorstruct Iteratorimport FoundationEssentials@frozen struct Datainit() Initialize an empty Data.
init<S>(_ elements: S) where S : Sequence, S.Element == UInt8 init?(base64Encoded base64Data: Data, options: Data.Base64DecodingOptions = []) Initialize a Data from a Base-64, UTF-8 encoded Data.
init?(base64Encoded base64String: String, options: Data.Base64DecodingOptions = []) Initialize a Data from a Base-64 encoded String using the given options.
init<SourceType>(buffer: UnsafeBufferPointer<SourceType>) Initialize a Data with copied memory content.
init<SourceType>(buffer: UnsafeMutableBufferPointer<SourceType>) Initialize a Data with copied memory content.
init(bytes: UnsafeRawPointer, count: Int) Initialize a Data with copied memory content.
init(bytesNoCopy bytes: UnsafeMutableRawPointer, count: Int, deallocator: Data.Deallocator) Initialize a Data without copying the bytes.
init(capacity: Int) Initialize a Data with the specified size.
init(contentsOf url: URL, options: Data.ReadingOptions = []) throws Initialize a Data with the contents of a URL.
init(count: Int) Initialize a Data with the specified count of zeroed bytes.
init(from decoder: any Decoder) throws init(repeating repeatedValue: UInt8, count: Int) Initialize a Data with a repeating byte pattern
var count: Int { get set }The number of bytes in the data.
var customMirror: Mirror { get }var debugDescription: String { get }A human-readable debug description for the data.
var description: String { get }A human-readable description for the data.
var endIndex: Data.Index { get }The end Index into the data.
var indices: Range<Int> { get }var regions: CollectionOfOne<Data> { get }var startIndex: Data.Index { get }The start Index in the data.
subscript(bounds: Range<Data.Index>) -> Data { get set } subscript<R>(rangeExpression: R) -> Data where R : RangeExpression, R.Bound : FixedWidthInteger { get set } subscript(index: Data.Index) -> UInt8 { get set } Sets or returns the byte at the specified index.
static func == (d1: Data, d2: Data) -> Bool Returns true if the two Data arguments are equal.
func advanced(by amount: Int) -> Data mutating func append(_ other: Data) mutating func append<SourceType>(_ buffer: UnsafeBufferPointer<SourceType>) Append a buffer of bytes to the data.
mutating func append(_ bytes: UnsafePointer<UInt8>, count: Int) mutating func append(contentsOf bytes: [UInt8]) mutating func append<S>(contentsOf elements: S) where S : Sequence, S.Element == UInt8 func base64EncodedData(options: Data.Base64EncodingOptions = []) -> Data Returns a Base-64 encoded Data.
func base64EncodedString(options: Data.Base64EncodingOptions = []) -> String Returns a Base-64 encoded string.
func copyBytes(to pointer: UnsafeMutablePointer<UInt8>, count: Int) Copy the contents of the data to a pointer.
func copyBytes<DestinationType>(to buffer: UnsafeMutableBufferPointer<DestinationType>, from range: Range<Data.Index>? = nil) -> Int This function copies the bytes in range from the data into the buffer. If the count of the range is greater than MemoryLayout<DestinationType>.stride * buffer.count then the first N bytes will be copied into the buffer.
func copyBytes(to pointer: UnsafeMutablePointer<UInt8>, from range: Range<Data.Index>) Copy a subset of the contents of the data to a pointer.
func encode(to encoder: any Encoder) throws func hash(into hasher: inout Hasher) The hash value for the data.
func index(after i: Data.Index) -> Data.Index func index(before i: Data.Index) -> Data.Index func makeIterator() -> Data.Iterator An iterator over the contents of the data.
mutating func replaceSubrange(_ subrange: Range<Data.Index>, with data: Data) Replace a region of bytes in the data with new data.
mutating func replaceSubrange<SourceType>(_ subrange: Range<Data.Index>, with buffer: UnsafeBufferPointer<SourceType>) Replace a region of bytes in the data with new bytes from a buffer.
mutating func replaceSubrange<ByteCollection>(_ subrange: Range<Data.Index>, with newElements: ByteCollection) where ByteCollection : Collection, ByteCollection.Element == UInt8 Replace a region of bytes in the data with new bytes from a collection.
mutating func replaceSubrange(_ subrange: Range<Data.Index>, with bytes: UnsafeRawPointer, count cnt: Int) mutating func reserveCapacity(_ minimumCapacity: Int) mutating func resetBytes(in range: Range<Data.Index>) Set a region of the data to 0.
func subdata(in range: Range<Data.Index>) -> Data Return a new copy of the data in a specified range.
