       | cannot have async fns in traits, making writing middleware and
       | services much more difficult to write. Along with that, async and
       | lifetimes, or unmet Send + Sync bounds leads to long, often
       | confusing compiler errors. Current runtimes require you to think
       | about blocking. While this is not as much of a problem for those
       | who have dealt with this from other languages, I cannot count the
       | number of times I have seen someone write `tokio::spawn(async {
       | users::get(conn) })` - blocking the executor. Mixing async and
       | sync, or even worse, mixing tokio and async-std is a pain.
       | Compared to Go and Javascript, Rust will be hard, there is no
       | denying that. I love Rust. As someone who understands and writes
       | lower-level async code, I do think it has a place in the web
       | world, and there is active work being done by the async-wg to
       | improve ergonomics. However, it's not there as a general-purpose
       | server-side language yet, and I am not sure it will ever be.
       | Sure, use it for certain services, or side projects you want to
       | have fun with. Is there ever going to be a "Rails for Rust"?
       | Probably not, but people will and _are_ trying :)
