Eclipse Corrosion vs Lapce

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.

Lapce is an open-source code editor written in Rust, available for Linux, macOS, and Windows. It uses a native graphical interface with GPU acceleration through Floem. For code intelligence, it combines Tree-sitter syntax highlighting with Language Server Protocol support for completion, diagnostics, and code actions. Developers can connect to a remote machine to work in an environment matching a production server, and the included terminal opens at the workspace path. The editor has built-in Vim-like modal editing and supports multiple cursors. Plugins can be written in any programming language that compiles to WASI, and the editor supports extensions. Downloads include Linux tar.gz builds for x86 and ARM, Windows system installer and portable x86 builds, and a universal macOS DMG. The product page displays version 0.4.2. Its documentation covers setup, settings, keybindings, modal editing, remote development, themes, terminal use, multiple cursors, syntax highlighting, and plugin development. The About page says Lapdev is maintained by the Lapce team and describes Lapce and Floem as open-source projects.
