rustup component add rust-analyzer

Catenary ships a built-in definition for rust-analyzer — no [lsp.server.*] config is needed. If rust-analyzer is on PATH (the rustup proxy installed by rustup component add rust-analyzer provides it), it works automatically.

To customise, add to ~/.config/catenary/config.toml:

[lsp.server.rust-analyzer]
env = { CLIPPY_DISABLE_DOCS_LINKS = "1" }

[lsp.server.rust-analyzer.initialization_options]
check.command = "clippy"
cargo.features = "all"
diagnostics.disabled = ["inactive-code"]

Setting CLIPPY_DISABLE_DOCS_LINKS=1 strips “for further information visit …” suffixes from clippy diagnostics, saving agent context tokens.

Notes

rust-analyzer is the official Rust language server
Installing via rustup ensures it stays in sync with your Rust toolchain
The rust-analyzer on PATH is the rustup proxy, which dispatches to the toolchain’s own rust-analyzer — so it tracks a project-level rust-toolchain.toml automatically
First run on a project may take time to index (watch for “Indexing” status)
