In Rust, making something copyable is always explicit. I like that a lot.
Copy has a very different meaning between the two languages. In rust the equivalent of a c++ copy is a clone() call for anything non trivial
...which is also explicit.
@BatmanAoD @Miaou It is just what you are used to.
In C++ everything is a copy. Sometimes the compiler optimizes it away. clang-tidy may help. Having a clone() is very C-like.
That's a common idiom but the default behaviour is still implicit copy, which, with VLAs and no smart pointers, makes things arguably worse than in c++
