Function Hash

expr/hasher.go:32–34

Hash returns a hash value for the given data type. Two types have the same hash if: - both types have the same kind - array types have elements whose types have the same hash - map types have keys and elements whose types have the same hash - user types have the same name if ignoreNames is false or

(dt DataType, ignoreFields, ignoreNames, ignoreTags bool)

//   - user types have the same attribute names and the attribute types have the same hash if ignoreFields is false
//   - object attributes have the same "struct:field:xxx" tags if ignoreTags is false
func Hash(dt DataType, ignoreFields, ignoreNames, ignoreTags bool) string {
	return *hash(dt, ignoreFields, ignoreNames, ignoreTags, make(map[*Object]*string))
}
