The autocomplete function doesn't work.

I use IntelliJ IDEA (community edition 2016.3) to develop in Rust, but after installing the Rust plugin, the code auto-complete function doesn't work:

I hope IntelliJ IDEA would give me a hint for String, but I still need me to write it myself. Did I miss something?

really? It did show me a list of hints after I typed Str. Perhaps you should check your settings of this plugin.

@framlog: "settings of this plugin.", could you elaborate this? Thanks very much!

You have created a project in a directory which is not a Cargo project (you have two separate ones inside instead). Our requirement for almost any feature is that IntelliJ project root (~/rust in your situation) is also Cargo project/workspace root (it has Cargo.toml). Thanks to this we can firmly invoke cargo to get all information we need.

tl;dr make separate projects inside each: hello_cargo and guessing_game :-)

@mkaput: Yes, you are definitely right! Thanks very much!
