Question about Enum Classes

[tranquil stone]

enum class NewType : int
{ APPLE, BANANA, ORANGE, MANGO, STRAWBERRY, CHERRY, WATERMELON }

void Foo::serialize_this(Serialize& serialize) 
{
serialize.get_int(static_cast<std::underlying_type_t<NewType>>(NewType::APPLE));

serialize.get_int(static_cast<std::underlying_type_t<NewType>>(NewType::BANANA));

serialize.get_int(static_cast<std::underlying_type_t<NewType>>(NewType::MANGO));
}

Hi can you please hint me how to remove the code repetition here and
static_cast<std::underlying_type_t<NewType>>(NewType::APPLE) Shorten this expression ?

Write a function/template and can that instead
C++23 will introduce a std::to_underlying to the standard library, but you can roll your own version

Alternatively since you kinda need to know that the underlying type is int to call the right function on your serializer, just cast to int directly

Alternatively, write a "serialize enum" function for your serializer
