Eclipse Corrosion vs Kate

Eclipse Corrosion is a Rust development plugin for the Eclipse IDE, available on Windows, macOS, and Linux. It connects to Rust Analyzer for code completion, hover documentation, diagnostics, and formatting, and supports Rust navigation. Cargo and Rustup integration includes a project wizard, toolchain management, TOML editing, and crate export. For debugging, Corrosion uses rust-gdb with Eclipse CDT GDB support for variable inspection, breakpoints, a GDB console, and expression execution. Its Unit Tests view tracks test execution and helps examine reports. Installation options include a packaged Eclipse IDE, an existing Eclipse IDE, Eclipse Marketplace, or 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 stated scope. The project is free and licensed under the Eclipse Public License 2.0. Its latest listed release is version 1.2.4, dated 2022-07-05.
