minus-squareporgamrer@programming.devlinkfedilinkarrow-up3·1 year agoTo me it’s not really excitement so much as “oh god how do i make this ridiculous language do the correct thing”. I’m way more scared of rogue implicit copy constructors. I wonder if cppfront has any plan to fix problems like implicit copy and pessimising move.
minus-squarecrispy_kilt@feddit.delinkfedilinkarrow-up0·1 year agoIn Rust, making something copyable is always explicit. I like that a lot.
minus-squareMiaou@jlai.lulinkfedilinkarrow-up0·1 year agoCopy 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
minus-squareFlorian Xaver@mastodon.sociallinkfedilinkarrow-up1·1 year ago@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.

…which is also explicit.
