Rust Analyzer for RustRover#
Rust Analyzer is good, and so does RustRover. However, the best is when you can combine them.
Usage#
You must have Rust Analyzer installed to use this plugin. The executable will then be detected and invoked automatically on file open.
Additionally, if you are using IntelliJ IDEA or PyCharm Community Edition, the LSP4IJ plugin must be installed and enabled. Once it is installed, change the running mode to LSP4IJ.
