About tauri-egui

tauri-egui is a Tauri plugin for using the egui library in a Tauri application via glutin. egui is a pure Rust GUI library that runs natively, recommended by the Tauri team for secure contexts such as password and secret interfaces.

Dependency

Component	Description	Version
tauri	runtime core
egui	immediate mode GUI library for Rust
tao	cross-platform application window creation library in Rust
glutin	low-level library for OpenGL context creation, written in pure Rust.

Example

use tauri::Manager;
use tauri_egui::{eframe, egui, EguiPluginBuilder, EguiPluginHandle};

struct LoginApp {
  password: String,
  on_submit: Box<dyn Fn(&str) -> bool + Send>,

  ) -> Self {
    Self {
      password: "".into(),
      on_submit: Box::new(on_submit),
    }

}

impl eframe::App for LoginApp {

        [ui.available_width(), 24.],
        egui::TextEdit::singleline(password).password(true),
