  • I could understand method = associated function whose first parameter is named self, so it can be called like self.foo(…). This would mean functions like Vec::new aren’t methods. But the author’s requirement also excludes functions that take generic arguments like Extend::extend.

    However, even the above definition gives old terminology new meaning. In traditionally OOP languages, all functions in a class are considered methods, those only callable from an instance are “instance methods”, while the others are “static methods”. So translating OOP terminology into Rust, all associated functions are still considered methods, and those with/without method call syntax are instance/static methods.

    Unfortunately I think that some people misuse “method” to only refer to “instance method”, even in the OOP languages, so to be 100% unambiguous the terms have to be:

    • Associated function: function in an impl block.
    • Static method: associated function whose first argument isn’t self (even if it takes Self under a different name, like Box::leak).
    • Instance method: associated function whose first argument is self, so it can be called like self.foo(…).
    • Object-safe method: a method callable from a trait object.





  • It’s funny because, I’m probably the minority, but I strongly prefer JetBrains IDEs.

    Which ironically are much more “walled gardens”: closed-source and subscription-based, with only a limited subset of parts and plugins open-source. But JetBrains has a good track record of not enshittifying and, because you actually pay for their product, they can make a profitable business off not doing so.
