Shipping Const Generics in 2020
It’s hard to believe that its been more than 3 years since I opened RFC 2000 , which defined the const generics for Rust. At the same time, reading the RFC thread, there’s also been a huge amount of change in this area: for one thing, at the time the RFC was written, const fns weren’t stable, and consts weren’t even…
