import Swift

@frozen struct UTF8View

A view of a string’s contents as a collection of UTF-8 code units.

@frozen struct String

A Unicode string value that is a collection of characters.

var count: Int { get }

var customMirror: Mirror { get }

Returns a mirror that reflects the UTF-8 view of a string.

var description: String { get }

var endIndex: String.UTF8View.Index { get }

The “past the end” position—that is, the position one greater than the last valid subscript argument.

var startIndex: String.UTF8View.Index { get }

The position of the first code unit if the UTF-8 view is nonempty.

subscript(r: Range<String.UTF8View.Index>) -> String.UTF8View.SubSequence { get }

subscript(i: String.UTF8View.Index) -> UTF8.CodeUnit { get }

Accesses the code unit at the given position.

func distance(from i: String.UTF8View.Index, to j: String.UTF8View.Index) -> Int

func index(_ i: String.UTF8View.Index, offsetBy n: Int) -> String.UTF8View.Index

func index(_ i: String.UTF8View.Index, offsetBy n: Int, limitedBy limit: String.UTF8View.Index) -> String.UTF8View.Index?

func index(after i: String.UTF8View.Index) -> String.UTF8View.Index

Returns the next consecutive position after i.

func index(before i: String.UTF8View.Index) -> String.UTF8View.Index

func withContiguousStorageIfAvailable<R>(_ body: (UnsafeBufferPointer<String.UTF8View.Element>) throws -> R) rethrows -> R?

typealias Element = UTF8.CodeUnit

typealias Index = String.Index

typealias SubSequence = Substring.UTF8View
