What Eclipse Corrosion is
Eclipse Corrosion is a free, open-source Rust development plugin for the Eclipse IDE, available on Windows, macOS, and Linux. It connects Rust Analyzer for completion, hover documentation, diagnostics, formatting, and Rust navigation. Cargo and Rustup tools support project setup, toolchain management, TOML editing, and crate export. For debugging, Corrosion uses rust-gdb with Eclipse CDT GDB support, including breakpoints, variable inspection, a GDB console, and expression execution. A Unit Tests view tracks test execution and helps examine reports. It can be installed as a packaged Eclipse IDE, added to an existing Eclipse installation, installed from Eclipse Marketplace, or obtained from 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 project’s current scope. The project uses the Eclipse Public License 2.0; its latest listed release is version 1.2.4, dated 2022-07-05.
Good

Who it suits
Corrosion suits Rust developers, from newcomers to experts, who use Eclipse and want integrated language, Cargo, testing, and debugging tools. It is less suited to users who need in-IDE Cargo crate management.
Verdict
Corrosion brings Rust language tools, testing, and debugging into Eclipse at no cost. Check the package-specific Git and terminal availability and the stated scope limit before choosing it.
