Route syntax with automatic data decoding is appealing
From 2 comments
Syntax is amazing! Hope (so much) to see it possible on beta soon. Maybe for somebody it's not a new thing, but for me this: ``` struct Message { contents: String, }…
EugeneOZ on HNEdit: should preface this by saying the framework looks really impressive. I've been looking for a Rust web framework to settle on and this is the most appealing. It's funny to…

Compile-time checking of route parameters
From 2 comments
Yes! Here's what happens when you don't do the right thing: ``` error: 'id' is declared as an argument... --> src/main.rs:8:9 | 8 | #[get("/<id>")] | ^^^^ error: ...but isn't in…
sbenitez on HNThis demonstrates the brilliance of Rust's syntax extensions. Not only is the code more readable and ergonomic, but also type safe. Errors or mismatches in implementations are…

Resembles Flask and is easy for simple tasks
From 2 comments
This looks very much like Flask, and Flask is one of my favorite ways of writing webapps because it's just so easy to do the simple things.
Manishearth on HNSince you mentioned "for somebody it's not a new thing": this looks a lot like Flask, if you're into Python (except for the type safety); I'm sure there's a Ruby equivalent. It…

Objections
Metaprogramming and syntax extensions can hinder clarity and debugging
From 3 comments
Sorry but I cannot agree. I work on the JVM and this pattern is great for "hello world" webapps but breaks down pretty quickly. When large parts of your logic like metrics,…
strictfp on HNI've worked on everything you mention and more, and I find the simplicity of say node.js or SparkJava very refreshing when coming from metaprogramming frameworks. Once you go…
strictfp on HNPersonally I don't like domain-specific sugared syntax. I prefer clarity above all, especially since I hope to spend the least possible amount of time in the networking domain,…

Documentation is sparse and has hidden gotchas with forms
From 1 comment
Being very excited about another Rust web framework, I've been trying to use this for the last few days. While the basics seem very interesting, there's a few large stumbling…

Landing page messaging does not explain why to use it
From 1 comment
I suppose this an advance for those already using Rust but the core message on the front page doesn't speak to me as a non-Rust person. FTA: Rocket is a web framework for Rust…

Better documentation and examples
From 2 comments
We're in the process of addressing discoverability of the crates.io ecosystem, which led to this RFC: https://github.com/rust-lang/rfcs/pull/1824 A quote from it: > By far, the…

Support for async futures
From 2 comments
It's my understanding that the current Rust web framework landscape is dealing with moving over to futures (example: https://github.com/hyperium/hyper/issues/934). The framework…

Middleware or filters for cross-cutting concerns
From 1 comment
I didn't see it in the docs, but does there exist a concept similar to java's servlet filters. For instance to check apikeys globally, perform compression, input validation, etc.…

Questions
How security is handled compared to other frameworks
From 3 comments
as someone who knows nothing about web development, does this framework emphasize security as much as rust itself does? how does this framework compare to other rust web…
bronz on HNI am not a web development guy, so this question might seem ridiculous: To me, it always seems that there are a lot of hazards in any web development project, security-wise: A…
eveith on HNedit: see replies to my comment. I mistook the Hyper pull request being merged for being in the latest release, but it isn't. Rocket uses Hyper for its HTTP server. So I checked…

Whether Rust is simple enough for scripting like Python
From 1 comment
One of my influences, Armin Ronacher, has been doing a lot of Rust work lately, so I've been thinking about looking at it more closely since I appreciate his Python tastes. Is…

Sinatra and Express

Syntax is why sinatra and express got bit. Just add a callback for your route and off you go.

Play framework

This looks pretty nice, it reminds me of Play! framework for Scala. I am curious to see if Rust or Swift will prevail for this kind of thing. Both have the opportunity to reach…
