Racer (Rust Auto-Complete-er) is a CLI utility that provides Rust code completion for editors and IDEs. It is no longer actively developed, and users are directed to rust-analyzer instead.
Use cases
- rust code completion in vim or emacs
- autocomplete for rust in my editor
- integrate rust completion into a lightweight editor
- eldoc-style rust completion
- complete rust function names and types while editing
When to choose
- you are stuck on a legacy editor setup that only supports racer
- you need completion for a very old Rust toolchain
When to avoid
- starting any new project - use rust-analyzer instead
- you want actively maintained tooling or stable Rust support (racer requires nightly)
