You can use 0.5.0-dev if you want stable rust.

I want to caveat this by first saying I’m a fan of Rust in general, but does one not see the irony in the article’s claim to the effect “yes, it’s ready as a Rails replacement”, yet requires you to use an unreleased dev version of a library to even build from a stable release of the language?

Yeah, and I don't know how anyone could claim its a Rails replacement. Diesel, warp, rocket et al are great but the DX and feature completeness aren't there yet.

That said, with Cargo using the unreleased version is as simple as changing `rocket = "0.4.5"` to `rocket = { git = "https://github.com/SergioBenitez/Rocket" }` so it's not like you even have to clone it manually. You can even specify branches if you urgently need a PR and patch entire workspaces with forked versions and so on.
