@elyracode/lsp-rust

Rust LSP integration for Elyra. Starts a rust-analyzer process per session and exposes semantic code navigation and diagnostics as agent tools — go-to-definition, find references, hover, and diagnostics for Rust and Cargo projects.

Prerequisites

rust-analyzer must be on your PATH (or installed via rustup, which places it in ~/.cargo/bin/).

rustup component add rust-analyzer

…or install a standalone binary from the rust-analyzer releases.

A Cargo.toml must exist in the project root. The extension does nothing if one is not found.

Note: rust-analyzer indexes the workspace on first use, which can take longer on large crates. The first rust_diagnostics/rust_hover call after a session starts may need a moment.

Installation

elyra install npm:@elyracode/lsp-rust

Available Tools

| Tool | Description | |------|-------------| | rust_definitions | Go to the definition of a Rust symbol at a given file position | | rust_references | Find all references to a Rust symbol across the project | | rust_diagnostics | Get Rust compiler/clippy-derived errors and warnings for a file | | rust_hover | Get type information and documentation for a symbol |

All tools accept 1-based line and column numbers and return human-readable text results.

Symbol-aware auto-context

After a successful edit to a .rs file, the extension proactively resolves unfamiliar-looking type/struct/trait names referenced in the new code via rust_analyzer's hover, and appends a short summary directly to the edit's own tool result — no extra rust_hover round trip needed to check "is this the shape I think it is".
