PirateSoftware doesn't use enums for whatever reason, instead he uses raw integer values with hand comments (and allegedly an Excel doc) on what is what, which is one of the reasons behind his awful code, which in turn lead to him not being able to ship his game.

Actually they're only enums if they're made in the Enümmär region of Germany, otherwise they're just sparkling integers.

Another comment on this post have declared enums outside of Rust being bad for not having tagged union capabilities.

Yeah but that's just edgelord behaviour.

You get those a lot with all kinds of programming languages, and Rust is certainly not know for having less of them.

It just it involves way more programmer socks and HRT jokes when it comes to Rust...

Reminds me of a codebase I used to work on which we had 899 variable limit and we couldn't name them, only number them. These were limitations of the language.

Each variable had to be assigned a 3 digit number but 1-100 were taken by internal stuff so only 101- 999 was allowed. So let's say you wanted to check if power was between 50 and 60 you would end up with like

#301 = 50;

#302 = 60;

#303 = powerSignal;

If #303 < #301 || #303 > #302: Display error

Continue process

Apparently PirateSoftware is someone who live-streams.

Roaches can’t enumerate

They are just named integers. The compiler takes care of all that.

But enumerators (aka. iterators) typically have nothing to do with enums, no?

[–] RustyNova@lemmy.world 1 points 17 minutes ago

We aren't talking about enums here? My bad

[–] dreadbeef@lemmy.dbzer0.com 1 points 1 hour ago

f# enums better

[–] nailbar@sopuli.xyz 3 points 2 hours ago (1 children)

Glances nervously at my own code using more and more enums now-a-days.

[–] RaphaelSchmitz@feddit.org 1 points 15 minutes ago

Not a problem, ignore the edgelording, you'll be fine.

A lot of people don't understand that readability is about how fast someone can correctly understand that whole class/file/etc afterwards. Sometimes using enums improves that, sometimes not.

For enums specifically, it is good to be aware what you do with them. Often it directly maps to a decision. E.g. enum ExportType with values JSON/XML/CSV - instead of passing an enum value to a big function with 3 different paths, you could have 3 classes that have a common interface, and pass one of those to the function to use. That is nicer sometimes, other times not.

Another thing is that enums are often used to have a small INT DB column, which is not supposed to represent a number (like for math and stuff) but different options. In that case, yeah enum is perfect to describe in code what those numbers actually mean.

But yeah, it all comes down to: After you write it, look at your code and see if it makes sense quickly - if not, adjust.

Please elaborate.

Enums in Rust are spicier unions, and Rust boosters like to paint it as the perfect way to do it, because it's the best language ever, with no faults. If you disagree, they'll try to frame you as a Lunduke fan and a bigot.

[–] RustyNova@lemmy.world 1 points 7 minutes ago

Never said that. In fact, enums have lots of issues that can add a lot of boilerplate code.

But actually having data associated with the type system instead of just a flag is a lot more powerful and less prone to errors than classic enums

You can also put functions on this union type that allows easy abstraction of what state the union is in

Iffind rust interesting but I don't use it enough to know anything deep about it.

All I know is that I am not made for c++.

Hell I can't keep track of pointers and scopes. And who the hell made templates?

[–] ZILtoid1991@lemmy.world 1 points 1 hour ago

Templates outside of D are a mess, and the reason why metaprogramming has a bad name. Templates inside D are easy to use, and its attempt at it is something more language should copy.
