Ah, nothing says "cutting-edge innovation" quite like a 7-year-old article on #state #machines in Rust! Dive into this riveting tale of #enums and structures, where #computer scientists bravely pave the way to a "hopeful future" by rehashing #CS101 topics. Seriously, Samuel, enums again?

I really, really like the django_enum package.

Imagine Django's TextChoices/IntegerChoices classes, but with the ability to encapsulate any additional information for each choice in one place.

I don't use it everywhere, but it's super useful in a number of use-cases.

Here are a few places where I've found django_enum makes things easier. See alt text for more detail about how I use of each of these.

Wow, a whole article explaining that #enums in #Rust can be optimized! Who would’ve thought that a #compiler might actually, you know, do its job? Next week: discovering that water is wet and that the sky is blue.

Fascinating that #TypeScript 's people are talking about getting rid of #enums (union types can handle most of the situations - someone recently wrote they consider TS enums a mistake), yet now we have #Javascript talking about putting them in JS using the TS syntax:

I read an article on LinkedIn arguing against using #enums in #Rails models, favoring simple strings instead. While I believe integer enums provide faster indexing, querying, and less storage use, I'm curious why strings would be preferred.
