The biggest limitation is that theBETTER_ENUMmacro can't be used inside a class. This seemsdifficult to remove. There is a workaround withtypedef(or C++11using): BETTER_ENUM(SomePrefix_Color,uint8_t, Red, Green, Blue)structtriplet{typedefSomePrefix_Color Color; Color r, g, b; }; tripl...
BETTER_ENUM(SomePrefix_Color,uint8_t, Red, Green, Blue) struct triplet {typedefSomePrefix_Color Color; Color r, g, b; }; triplet::Color color; You can, however, useBETTER_ENUMinside a namespace. The macro has a soft limit of 64 declared constants. You can extend it by followingthese...

At the moment, several parts of Enum's and Categorical's are broken in the conjunction with Parquet reading and writing. This mostly stems from the fact that Polars does not use the arrow Dictionary type to store data contained in enums and categoricals. Instead, it chooses to store them ...
C++ has from the beginning attempted to improve on the type system of C, adding features like classes that let you build better types and enums, which eliminate the need for some uses of the preprocessor (which is not at all type safe). C++ also performs fewer implicit type conversions ...
Now that’s much better! Adding Description Support Now that we have our enum binding working perfectly without the need for that silly ObjectDataProvider, we can improve our enum experience. It is very common to have a enum to represent the values, while at the same time, give the enum ...
Is there a better way to represent enum with same values? class FuzzyTime(Enum): morning = 1 dawn = 2 noon = 3 midday = 4 afternoon = 5 evening = 6 sunset = 7 dusk = 8 night = 9 In those cases, I want to represent morning & dawn, noon & midday, evenning, sunset, dusk &...

[.Net] 通过反射,给Enum加备注 今天和大家分享一个给Enum加备注的技巧,话不多说,先上一段代码: namespace TestReflector.Model.Entities { public class UserInfo { public int Id { get; set; } public string Name { get; set; } public UserStatusEnum UserStatus { get; set; }...
