In all this time, maestro Andrei Alexandrescu was right when he said Rust feels like it "skipped leg day" when it comes to concurrency and metaprogramming capabilities. Tim Sweeney was complaining about similar things, saying about Rust that is one step forward, one step backward. These problems will be evident at a later time, when it will be already too late. I will continue experimenting with Rust, but Zig seems to have some great things going on, especially the colourless functions and the comptime thingy. Its safety story does not dissapoint also, even if it is not at Rust's level of guarantees.
And Zap (scheduler for Zig) is already faster than Tokio.
Zig and other recent languages have been invented after Rust and Go, so they could learn from them, while Rust had to experiment a lot in order to combine async with borrow checking.
So, yes, the async situation in Rust is very awkward, and doing something beyond a Ping server is more complicated than it could be. But that’s what it takes to be a pioneer.
D and Zig have dynamically typed generics (templates/"comptime thingy"), while Rust has statically typed generics. A lot of people confuse this for Rust having less powerful generics. It's simply a different approach: the dynamic vs. static types distinction, at the type level instead of the value level.
