Constants

const (
	KB = 1 << 10
	MB = 1 << 20
	GB = 1 << 30
	TB = 1 << 40
)

const KVPairQuote = '\''

Variables

var UTF8Len = utf8.RuneCountInString

UTF8Len is an alias of utf8.RuneCountInString which returns the number of runes in s. Erroneous and short encodings are treated as single runes of width 1 byte.
