Functions

func PeekRune

func PeekRune(runescanner io.RuneScanner) (r rune, size int, err error)

PeekRune returns the next rune (from the underlying io.RuneScanner) without advancing the reader. Although technically, it does temporarily advance the io.RuneScanner, and then unadvances it. PeekRune uses io.RuneScanner's ReadRune and UnreadRune to peek.
