Method CreateNull

eval/public/cel_value.h:183–183

We will use factory methods instead of public constructors The reason for this is the high risk of implicit type conversions between bool/int/pointer types. We rely on copy elision to avoid extra copying.

  // between bool/int/pointer types.
  // We rely on copy elision to avoid extra copying.
  static CelValue CreateNull() { return CelValue(NullType()); }

  // Transitional factory for migrating to null types.
  static CelValue CreateNullTypedValue() { return CelValue(NullType()); }
