Function Equal

expr/types.go:288–290

Equal compares the types recursively and returns true if they are equal. Two types are equal if: - both types have the same kind - array types have elements whose types are equal - map types have keys and elements whose types are equal - objects have the same attribute names and the attribute types

(dt, dt2 DataType)

// as the former may return true for two user types with different names and
// thus with different hash values.
func Equal(dt, dt2 DataType) bool {
	return Hash(dt, false, true, true) == Hash(dt2, false, true, true)
}

// DataType implementation
