Rustext

Rustext is an ultra-fast, native code and text editor designed for high performance, built entirely in 100% pure Rust using only the standard library (std::*). It features zero dependencies, allowing for a compact binary size of approximately ~650 KB and an impressive startup time of around 2 milliseconds. Rustext utilizes a Piece Table buffer architecture for efficient memory management and quick operations, ensuring effective handling of UTF-8 multibyte characters and symbols.

Inspired by the speed of Sublime Text and the modern ergonomics of VS Code/Zed, Rustext provides a smooth native development experience with reduced memory usage compared to conventional editors. Ideal for developers, it integrates a full Language Server Protocol (LSP) suite which supports 10 different programming languages including Rust, Python, and C/C++, facilitating advanced code editing features such as syntax highlighting, code linting, and inline error detection.

Key Features

• Ultra-Low Latency Performance: Experience the editorial speed with launch times of ~2 ms, ensuring immediate access to tools and projects, thus enhancing productivity.

• Zero External Dependencies: A standalone binary compiled without external libraries, reducing the risk of security vulnerabilities associated with third-party packages.

• High-Performance Buffer Management: The Piece Table model allows for efficient memory use and accelerated search/replace operations without unnecessarily copying data.

• Multi-Cursor Editing: Use parallel editing features with instant cursor synchronization, aligning with modern coding styles allowing easy editing across multiple lines.

• Live Git Integration: Featuring a built-in Git gutter showing real-time diffs, inline blame annotations, and quick hunk diff popups for seamless version control collaboration.

• Dynamic Theming: Customize the visual presentation with a robust theming system that supports hot reloading and easy integration of user-defined themes.

• Interactive Terminal: Utilize an embedded terminal for executing commands and tests without leaving the editor, enhancing workflow efficiency.

• Advanced Syntax Highlighting: Language-specific syntax support for various coding languages with semantic highlighting and intelligent comment syntax for clarity and readability.

• Integrated Workspace Management: Manage projects and files efficiently with a sidebar file explorer and instant access to recent files, making project navigation intuitive.

Usage Example

Here's how to launch Rustext and start coding without external dependencies:
