Some things that are "better" with this BetterPromise implementation:

• BetterPromise # then(..) accepts a BetterPromise (or Promise) instance passed directly, instead of requiring a function to return it, so that the promise is linked into the chain.

  var p = BetterPromise.resolve(42);
  
  var q = Promise.resolve(10);
  
  p.then(console.log).then(q).then(console.log);

Looking into the Future

futures-rs is the library which will hopefully become a shared foundation for everything async in Rust. However it's already become renowned for having a steep learning curve, even for experienced Rustaceans.

I think one of the best ways to get comfortable with using a library is to look at how it works internally: often API design can seem bizarre or impenetrable and it's only when you put yourself in the shoes of the library author that you can really understand why it was designed that way.

In this post I'll try to put down on "paper" my understanding of how futures work and I'll aim to do it in a visual way. I'm going to assume you're already somewhat familiar with Rust and why futures are a useful tool to have at one's disposal.

For most of this post I'll be talking about how things work today (as of September 2017). At the end I'll touch on what's being proposed next and also make a case for some of the changes I'd like to see.

Deploy Rocket using Letsencrypt and nginx

Information

This guide uses the domain your-domain.tld and its www. prefixed version. It starts the rocket application on 127.0.0.1:1337 and as the user www-data. The proxy listens on port 80 and 443 though.
If you need other values, update them accordingly in your nginx and systemd configs.

Prerequisites

You need to have nginx, certbot and rust installed.
