They have : https://www.rust-lang.org/ides.html https://www.rust-lang.org/ides.html >We propose a new tool, an 'oracle' which takes input from the compiler, maintains a project-wide view of the code and it's type information, and provides data about the project to IDEs and other tools. The oracle is a long-running daemon and presents an API via IPC. Which is great idea. But it is not implemented yet (AFAIK). personal opinion : Rust with this pace, will be absolutely one of the best language in term of usage/tools in next 5 year.
