struct StaticString An simple string designed to represent text that is "knowable at compile-time". Logically speaking, each instance looks something like this: enum StaticString { case ASCII(start: UnsafePointer<UInt8>, length: Int) case UTF8(start: UnsafePointer<UInt8>, length: Int) case Scalar(UnicodeScalar) } Inheritance DebugPrintable, ExtendedGraphemeClusterLiteralConvertible, Printable, StringLiteralConvertible, UnicodeScalarLiteralConvertible View Protocol Hierarchy → Import import Swift Initializers init() Create an empty instance. Declaration init() init(_builtinExtendedGraphemeClusterLiteral:byteSize:isASCII:) Declaration init(_builtinExtendedGraphemeClusterLiteral start: Builtin.RawPointer, byteSize: Builtin.Word, isASCII: Builtin.Int1) init(_builtinStringLiteral:byteSize:isASCII:) Declaration init(_builtinStringLiteral start: Builtin.RawPointer, byteSize: Builtin.Word, isASCII: Builtin.Int1) init(_builtinUnicodeScalarLiteral:) Declaration init(_builtinUnicodeScalarLiteral value: Builtin.Int32) init(extendedGraphemeClusterLiteral:) Create an instance initialized to value. Declaration init(extendedGraphemeClusterLiteral value: StaticString) init(stringLiteral:) Create an instance initialized to value. Declaration init(stringLiteral value: StaticString) init(unicodeScalarLiteral:) Create an instance initialized to value. Declaration init(unicodeScalarLiteral value: StaticString) Instance Variables var byteSize: Word If self stores a pointer to ASCII or UTF-8 code units, the length in bytes of that data. If self stores a single Unicode scalar value, the value of byteSize is unspecified. Declaration var byteSize: Word { get } var debugDescription: String A textual representation of self, suitable for debugging. Declaration var debugDescription: String { get } var description: String A textual representation of self. Declaration var description: String { get } var hasPointerRepresentation: Bool true iff self stores a pointer to ASCII or UTF-8 code units Declaration var hasPointerRepresentation: Bool { get } var isASCII: Bool true if self stores a pointer to ASCII code units. If self stores a single Unicode scalar value, the value of isASCII is unspecified. Declaration var isASCII: Bool { get } var stringValue: String Return a String representing the same sequence of Unicode scalar values as self does. Declaration var stringValue: String { get } var unicodeScalar: UnicodeScalar The stored Unicode scalar value Requires: self stores a single Unicode scalar value. Declaration var unicodeScalar: UnicodeScalar { get } var utf8Start: UnsafePointer<UInt8> A pointer to the beginning of UTF-8 code units Requires: self stores a pointer to either ASCII or UTF-8 code units. Declaration var utf8Start: UnsafePointer<UInt8> { get } Instance Methods func withUTF8Buffer(_:) Invoke body with a buffer containing the UTF-8 code units of self. This method works regardless of what self stores. Declaration func withUTF8Buffer<R>(body: @noescape (UnsafeBufferPointer<UInt8>) -> R) -> R
