Productivity of Rust teams at Google
(programming.dev)
Slide with text: “Rust teams at Google are as productive as ones using Go, and more than twice as productive as teams using C++.”
In small print it says the data is collected over 2022 and 2023.
There's nothing wrong with putting Rc<_> or Rc<RefCell<_>> around data if you don't want to fight the borrow checker or think about lifetimes even if you know it can be written without.
Or even just clone. Depending on use case the performance cost would be negligible.
It's mainly the visual pollution that bothers me. Wrapping everything in the reference counting smart pointers just because you can't be bothered dealing with the borrow checker seems like an antipattern
I don't know why so many recommend Rc or Arc as a catchall. 90% of the time if you want to avoid the borrow checker then a clone or copy is good enough.
