Built for you, maintained for Tauri. ### Cargo Features TAO provides the following features, which can be enabled in your `Cargo.toml` file: - `serde`: Enables serialization/deserialization of certain types with [Serde](https://crates.io/crates/serde). - `tray`: Enables system tray and more menu item variants on **Linux**. This feature requires either `libayatana-appindicator` or `libappindicator` package installed. You can still create those types if you disable it. They just don't create the actual objects. We set this flag because some implementations require more installed packages. ## Platform-specific notes ### Android This library makes use of the [ndk-rs](https://github.com/rust-windowing/android-ndk-rs) crates, refer to that repo for more documentation. Running on an Android device needs a dynamic system library, add this to Cargo.toml: ```toml [[example]] name = "request_redraw_threaded" crate-type = ["cdylib"] ``` And add this to the example file to add the native activity glue: ```rust #[cfg_attr(target_os = "android", ndk_glue::main(backtrace = "on"))] fn main() { ... } ``` And run the application with `cargo apk run --example request_redraw_threaded` ### Linux Gtk and its related libraries are used to build the support of Linux. Be sure to install following packages before building: #### Arch Linux / Manjaro: ```bash sudo pacman -S gtk3 ``` For `tray` feature: ```bash sudo pacman -S libappindicator-gtk3 ``` #### Debian / Ubuntu: ```bash sudo apt install libgtk-3-dev ``` For `tray` feature, choose one of following packages: ```bash sudo apt install libappindicator3-dev ``` ```bash sudo apt install libayatana-appindicator3-dev ``` #### macOS To ensure compatibility with older macOS systems, TAO links to CGDisplayCreateUUIDFromDisplayID through the CoreGraphics framework. However, under certain setups this function is only available to be linked through the newer ColorSync framework. So, TAO provides the `TAO_LINK_COLORSYNC` environment variable which can be set to `1` or `true` while compiling to enable linking via ColorSync. ### Acknowledgement This is a fork of [winit](https://crates.io/crates/winit) which replaces Linux's port to Gtk. We need it not only because of webkit2gtk, but also a lot of Desktop Environment features like menu bar, system tray, global shortcuts etc. In the future, we want to make these features more modular as separate crates. So we can switch back to winit and also benefit the whole community.
