rust.vim is a Vim plugin that provides Rust language support including file detection, syntax highlighting, formatting, and error checking integration.
The plugin solves the problem of editing Rust code in Vim without native language support. It detects Rust files automatically and applies appropriate syntax highlighting. For developers who want to check code for errors while editing, it integrates with Syntastic and automatically registers cargo as a syntax checker. The plugin also enables code formatting through the :RustFmt command, which calls rustfmt if installed, with an option to format automatically on save. Additional features include Tagbar integration for source browsing and a :RustTest command to run individual tests under the cursor in Cargo projects.
The tool suits developers who use Vim as their primary editor for Rust projects and want language-specific conveniences without switching to a heavier IDE. It works with multiple plugin managers including Vim8 packages, Vundle, Pathogen, vim-plug, dein.vim, and NeoBundle. The plugin requires Vim 8 or higher for full functionality, though some features may work on earlier versions. The README does not compare it to alternative Rust editing solutions.
The project maintains active engagement with its user base through comprehensive built-in documentation accessible via the :help system. The plugin integrates with established Vim ecosystem tools like Syntastic, Tagbar, and webapi-vim rather than reimplementing their functionality. Development activity shows responsiveness to user needs across multiple plugin manager ecosystems and compatibility with evolving Rust tooling like rustfmt and cargo.
