intellij-idea - 如何让 Rust IntelliJ IDEA 插件显示自动完成建议？

Question

我使用 IntelliJ IDEA 在 Rust 中进行开发，但是在安装 Rust plugin 之后，代码自动完成功能不起作用:

我希望IntelliJ IDEA能给我一个String的提示，但我还是需要自己写。我错过了什么吗？

mkaput 赋予权利 answer :

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 :-)
