Traits now support async fn and -> impl Trait (with some limitations), the compiler got faster, version = in Cargo.toml is now optional, and many small functions have been stabilized!

You could argue that C++'s new is Rust's Box::new, and delete is replaced by RAII. Same concepts but way better ergonomy.

[-] arades@feddit.ch 1 points 11 months ago

box::new is pretty directly analogous to std::make_unique (factory for unique_ptr), in general rust’s heap allocating types map to c++’s smart pointer types, which are basically universally recommended over raw new/delete. So another column where rust just gives you the one best C++ feature where it still has 4 supported versions.
