Static Methods

static func encode(_:inout:)

Encode a UnicodeScalar as a series of CodeUnits by put'ing each CodeUnit to output.

Declaration

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.
