struct UTF8 A codec for UTF-8. Inheritance UnicodeCodecType View Protocol Hierarchy → Associated Types CodeUnit = UInt8 A type that can hold code unit values for this encoding. Import import Swift Initializers init() Declaration init() Static Methods static func encode(_:inout:) Encode a UnicodeScalar as a series of CodeUnits by put'ing each CodeUnit to output. Declaration static func encode<S : SinkType where CodeUnit == CodeUnit>(input: UnicodeScalar, inout output: S) static func isContinuation(_:) Return true if byte is a continuation byte of the form 0b10xxxxxx Declaration static func isContinuation(byte: CodeUnit) -> Bool Instance Methods mutating func decode(inout:) Start or continue decoding a UTF sequence. In order to decode a code unit sequence completely, this function should be called repeatedly until it returns UnicodeDecodingResult.EmptyInput. Checking that the generator was exhausted is not sufficient. The decoder can have an internal buffer that is pre-filled with data from the input generator. Because of buffering, it is impossible to find the corresponing position in the generator for a given returned UnicodeScalar or an error. next: a generator of code units to be decoded. Declaration mutating func decode<G : GeneratorType where CodeUnit == CodeUnit>(inout next: G) -> UnicodeDecodingResult
