Eclipse Corrosion
What it is
Eclipse Corrosion is a free, open-source Rust development plugin for the Eclipse IDE on Windows, macOS, and Linux. It integrates Rust Analyzer for code completion, documentation on hover, diagnostics, formatting, and navigation. Cargo and Rustup tools provide a project wizard, toolchain management, TOML editing, and crate export. Debugging uses rust-gdb with Eclipse CDT GDB support for breakpoints, variable inspection, a GDB console, and expression execution. A Unit Tests view monitors test execution and helps examine reports. Installation options include a packaged Eclipse IDE, adding the plugin to an existing Eclipse IDE, Eclipse Marketplace, and a p2 repository. Corrosion can install the Rust toolchain on Linux and macOS. Git integration and an embedded terminal are available only in the Corrosion Package. In-IDE Cargo crate management is outside the current scope. The project uses the Eclipse Public License 2.0, and the latest listed release is version 1.2.4 dated 2022-07-05.
