Method Next

scode/iter.go:21–36

Next returns the body of the next value along with a boolean that is true if the value is a container. It returns an empty slice for an empty or zero-length value and nil for a super null value. The container boolean is not meaningful if the returned Bytes slice is nil. Next panics if the next va
