Rust Switcher

Rust Switcher is a Windows 11 utility that helps convert text between RU and EN keyboard layouts.

It was created as an open-source alternative to Punto Switcher and Caramba Switcher with a clear privacy requirement: keyboard input stays on your device. No telemetry, no usage analytics, and no data uploads. Text conversion works offline; the application does not send your text or other user data to the developer or third parties.

Features

• Convert selected text (RU↔EN)
• Convert the last typed sequence via a hotkey ("smart" conversion also handles selection)
• Auto-convert the last word while typing (can be disabled in Settings; runtime toggle starts paused)
• Tray icon and quick actions menu
• Light and dark UI themes
• Settings are saved to a config file
• Autostart

Requirements

• Windows 11
• Rust nightly (see rust-toolchain.toml)
• MSVC toolchain (Visual Studio 2022 Build Tools)

Install

Via cargo

cargo install rust-switcher

From GitHub Releases

Download rust-switcher.exe from Releases.

Configuration

The config file is stored at:

• %APPDATA%\RustSwitcher\config.json

Default hotkey sequences:

• Convert last word: double tap Left Shift
• Convert last sequence: double tap Left Alt
• Convert selection: double tap Left Shift
• Autoconvert toggle: double tap Right Ctrl
• Switch layout: CapsLock

To remove a binding, focus its hotkey field and press Backspace or Delete.

Privacy

Your input stays on your device. Rust Switcher processes keyboard input and selected text locally and does not collect telemetry or usage analytics. It does not upload typed text, selections, input history, or preferences to the developer or third parties.

Recent input is held temporarily in memory to support conversion; preferences are saved locally. The privacy policy explains this local processing, retention, clipboard behavior, and development logging.

Pausing or disabling AutoConvert leaves keyboard tracking and manual hotkeys running. To stop all processing, right-click the tray icon and choose Exit; closing the settings window only hides it.

Development

This project includes a ready-to-use bacon.toml for a fast development loop.

Bacon hotkeys (from bacon.toml)

• d dev-long
• r release-long
• t test-long
• p dushnota

What these jobs do:

• dev-long: fmt check, clippy, build (with debug tracing), run the app
• release-long: fmt check, clippy, release build, run the app
• test-long: fmt check, clippy, run tests
• dushnota: strict clippy

Logging (development only)

$env:RUST_LOG="trace"
cargo +nightly run -F debug-tracing
