That’s silly. Luckily, I don’t think this was the same situation. This was at a university and they had classes with other languages. The beginner classes were split into two variants, where some students (mostly CS students) learned C, and other students (economy, etc.) learned Python. I suppose they figured it was more useful to them or something.
I was a teacher’s assistant in beginner’s programming at university for a bit. I expected them to learn C, which I knew enough of, but I got assigned to a group that learned Python instead. I had never used Python at the time. I ended up having to speed learn it while trying to teach it, to not be completely useless.
Det är ändå redan för sent. Det är buskens hus nu.
That’s definitely part of “the deal” with MIT and Apache. The other end of it is that they shouldn’t really expect to get anything more than what the authors are willing to give.
Right, there may be too many unknowns involved. 🤔

Option<T> has a From<T> implementation that lets you write Option::from($file_path).map(|path| path.to_string()) to accept both cases in the same expression.

A “mantra” more programmers should have is to fix the cause of the issue, and not just the symptoms. You have to understand what the problem is to be able to fix it.
Simple features are often complex to make, and complex features are often way too simple to make.
That’s nice to hear! And the Ok* color spaces are indeed quite neat
ICC profiles are definitely part of the field, but that’s sort of a topic of its own. At least in terms of scope. The color space rabbit hole is so deep that I never got as far as including them. There are other crates that go into those parts and it should be easy to bridge between them and Palette.
I would say Palette is more for the “business logic” of working with colors, so converting, manipulating and analyzing. The difference from ICC profiles when converting with Palette is that you need to know more about the source and destination color spaces during compile time. ICC profiles use more runtime information.
Palette could be used for applications like image manipulation programs, 3D rendering, generative art, UI color theme generation, computer vision, and a lot more. A lot of people also use it for smaller tasks like converting HSL input to RGB output or making gradients.
Förutom att välja de som verkar mest intressanta (finska vinterkriget är en bra klassiker) skulle jag också säga att man kan börja med de senaste och gå bakåt. De har en del repriser med bättre ljudkvalitet som man lätt missar annars. Enstaka serier är de enda man kan behöva se till att man börjar i rätt ände av, men de är tydligt numrerade eller ihopklippta.
It may be possible to use the Any trait to “launder” the value by first casting it to &Any and then downcasting it to the generic type.
let any_value = match tmp_value {
serde_json::Value::Number(x) => x as &Any,
// ...
};
let maybe_value = any_value.downcast_ref::< T >();
I haven’t tested it, so I may have missed something.
Edit: to be clear, this will not actually let you return multiple types, but let the caller decide which type to expect. I assumed this was your goal.
My shower has its own favorite temperature and will slowly readjust itself to it.
Absolutely, I didn’t mean to suggest otherwise. :) I’m just giving a bit of context and perspective from someone who has used it for a while.
Static types aside, the file system has a lot of failure cases, which every language is affected by, and Rust makes them very visible. This can indeed feel like a lot, but it’s an intentional feature and makes more sense in larger projects. I guess the feeling may get amplified by the author’s style of long form posts with a lot of details.
Error handling in practice contains a lot of “let the caller deal with it”, using the ? operator to pass errors up the call stack. The more verbose options are for when you need to actually handle it.
Reject C, return to assembly. Structured programming is the true oppression our generation never talks about.
