Show HN: Rocket – Web Framework for Rust
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 blocks ready for anyone who might want to "get serious" with it.<p>Documentation is very sparse. Indeed, the linked to page seems to be the primary documentation repository. This is particularly painful for a brand new project, because googling is wholly useless at this point (the only relevant results being the linked-to page). You can try to infer things from the API, but there's a lot that I would refer to as "hidden gotchas" which you'll only learn about through experimentation or by reading the source.<p>For example, consider the FromForm functionality. Does it decode url-encoded values? Turns out the answer is: maybe. If your struct defines the field as a String then the input will be url-decoded, but if you define the field as a str then it won't be. FromForm only works at all if the submission is of content-type 'application/x-www-form-urlencoded', failing entirely 'multipart/form-data' for example -- I have no idea how you're meant to go about parsing a multipart form besides doing it manually using just the raw post-data string as input. Also, good luck parsing anything with a checkbox (as their code example does) -- if the checkbox is checked, no problem, the field is populated with 'true'. But if the checkbox is left unchecked, then you get a parse failure because you're "missing" a field. There may be a way to work around this but if there is it isn't well documented and I haven't read through that part of the rocket source yet.
