Macro to enable bitwise operations for scoped enums (enum struct/class).

To use this, add the line JUCE_DECLARE_SCOPED_ENUM_BITWISE_OPERATORS (MyEnum) after your enum declaration at file scope level.

e.g.

enum class MyEnum
{
    one     = 1 << 0,
    two     = 1 << 1,
    three   = 1 << 2
};
 
JUCE_DECLARE_SCOPED_ENUM_BITWISE_OPERATORS (MyEnum)
 
MyEnum e = MyEnum::one | MyEnum::two;
 
bool hasTwo = (e & MyEnum::two) != MyEnum{}; // true
bool hasTwo = hasBitValueSet (e, MyEnum::two); // true
 
e = withBitValueCleared (e, MyEnum::two);
 
bool hasTwo = hasBitValueSet (e, MyEnum::two); // false
