Function PrettyPrintValuesWithTypes

pkg/util/encoding/encoding.go:2134–2160

PrettyPrintValuesWithTypes returns a slice containing each contiguous decodable value in the provided byte slice along with a slice containing the type of each value. The directions each value is encoded may be provided. If valDirs is nil, all values are decoded and printed with the default directio

(valDirs []Direction, b []byte)
