What Eclipse Corrosion is

Eclipse Corrosion is a free, open-source Rust development plugin for the Eclipse IDE, licensed under the Eclipse Public License 2.0. It connects Rust Analyzer for code completion, hover documentation, diagnostics, formatting, and navigation. Cargo and Rustup tools support project setup, toolchain management, TOML editing, and crate export; installing the Rust toolchain through Corrosion is available on Linux and macOS. For debugging, it uses rust-gdb with Eclipse CDT GDB support for breakpoints, variable inspection, a GDB console, and expression execution. A Unit Tests view follows test runs and helps examine reports. Corrosion can be installed as a packaged Eclipse IDE, added to an existing Eclipse installation, installed through Eclipse Marketplace, or obtained from a p2 repository. 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 Eclipse project page lists version 1.2.4, dated 2022-07-05, as its latest release.
