rust-analyzer-lsp — Claude Code plugin for Rust
Wires the rust-analyzer language server into Claude so the agent can navigate and analyse Rust code.
/plugin install rust-analyzer-lsp@claude-plugins-official
/plugin marketplace add anthropics/claude-plugins-officialWhat rust-analyzer-lsp does
The plugin connects Claude to rust-analyzer, the Rust language server. The agent gets code navigation and error analysis for .rs files.
The server itself is installed separately. With rustup that is rustup component add rust-analyzer; on macOS there is brew install rust-analyzer; on Linux you can use sudo apt install rust-analyzer or sudo pacman -S rust-analyzer. The plugin will not do anything until the binary is on your PATH, so check that rust-analyzer runs from the terminal first.
This is for Rust projects. In a JavaScript or Python repo there is nothing for it to talk to, so skip it.
What it helps with
- jump to a function definition in an unfamiliar Rust crate
- list every place a type is used
- work through compiler errors without leaving the chat
- check a method signature without opening the docs
Example prompts for the agent
- Show me where this trait is defined and which types implement it
- Find every call site of this function
- Explain the compile error in
src/main.rs
