Variables

var (
	// EqualPair 扫描 K=V这类形式的Pair字串
	EqualPair = NewPair('=',
		func(r rune) bool {
			return unicode.IsSpace(r) || r == '"'

	// ColonPair 扫描 K:V 这类形式的Pair字串

预定义Pair扫描对象

var (
	// 逗号分割
	Comma = NewScanner(',', unicode.IsSpace)
	// 分号分割
	Semicolon = NewScanner(';', unicode.IsSpace)
	// 空格分割
	Space = NewScanner(' ', nil)
	// 行分割
	Line = NewScanner('\n', unicode.IsSpace)
)
