In their own words
Eclipse Corrosion
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.
Qt Creator
Qt Creator is an IDE for making applications for desktop, embedded, and mobile systems, as well as web browsers. It supports work from project setup and interface design through coding, building, deployment, running, and debugging. The editor offers semantic highlighting, syntax checks, code completion, search, and refactoring. It understands C++ and QML, with some Python language services when a language server is available. Build integrations cover CMake, qmake, Qbs, and Autotools; generic projects can use configurable build commands. Integrated debuggers and analysis tools can help investigate memory leaks, profile execution, and analyze CPU use. Testing support includes Boost.Test, Catch2, Google Test, Qt Quick Test, Qt Test, and CTest. Qt Creator supports AI agents; its documentation lists GitHub Copilot and an MCP Server extension. An open-source version is available at free, subject to LGPL/GPL obligations for Qt framework use. Qt’s commercial evaluation lasts 10 days and is for evaluation, not production or product development. Commercial use requires an active license for each developer, and Qt-based device distribution may also need licenses.
