  • I think one thing to mention is that Rust is highly specific in what it does. In most of the examples you mentioned, string types, tokio::main, you can essentially just say that rust is more explicit. When initializing an integer variable in C using int, it’s not specified what use the integer is or whether it’s signed or not. i32, uint16_t you can see how it’s specified. Using tokio::main before your main function just specifies that you’re using the tokio asynchronous executor for your async code. In the case of string types, they all have different implementations which just help with being specific.

    The reason I like Rust is because I know what’s happening when I read it. Did I have to read the whole async book to understand how the tokio::main stuff works? Yes. But now I understand exactly how it works. The problem I have with using Javascript is that it doesn’t have that high amount of explicitness(is that a word?). At the end of the day, if you’re using it for a personal project or you’re arguing for language supremacy, it really just comes down to personal preference.













  • The article made a few good points, but a good amount of it was conjecture. I liked the part about comparing the two functions and showing that exceptions are faster but I think a big thing he’s not getting is readability. Even in the functions he showed, you can directly see that the one using std::expected has the happy path and error path directly in the function signature, whereas the exception one doesn’t.

    As for the “error kind” trap he was talking about, that definitely exists, but ignores the fact that you can also get this same kind of error from exceptions. I’ve definitely gotten exceptions that I didn’t understand from Python or Java libraries, but it’s not a problem with exceptions but a problem with how they’re shown. If there’s nothing to tell me that I should have thought of that error, it shouldn’t be an expectation for a dev to have thought of it.
