本文介绍了如何在Rust项目中通过Cargo.toml添加winit依赖，并在main.rs中创建一个简单的窗口程序，处理鼠标点击和移动事件。

一、首先，在Cargo.toml文件中添加winit作为依赖项：

[dependencies]  
winit = "0.25" # 请检查最新版本

二、在main.rs中编写程序：

use winit::{  
    event::{Event, MouseInput, MouseMotion, WindowEvent},  
    event_loop::{ControlFlow, EventLoop},  
    window::WindowBuilder,  
};  
  
fn main() {  
    let event_loop = EventLoop::new();  
    let window = WindowBuilder::new().build(&event_loop).unwrap();  
  
    event_loop.run(move |event, _, control_flow| {  
        *control_flow = ControlFlow::Wait;  
  
        match event {  
            Event::WindowEvent {  
                event: WindowEvent::CloseRequested,  
                window_id,  
            } if window_id == window.id() => *control_flow = ControlFlow::Exit,  
            Event::WindowEvent {  
                event: WindowEvent::MouseInput { state, button, .. },  
                window_id,  
            } if window_id == window.id() => {  
                if button == MouseButton::Left && state == ElementState::Pressed {  
                    println!("Mouse button pressed.");  
                }  
            }  
            Event::WindowEvent {  
                event: WindowEvent::MouseMove { position, .. },  
                window_id,  
            } if window_id == window.id() => {  
                println!("Mouse moved to: {:?}", position);  
            }  
            _ => return,  
        }  
    });  
}

导入可能需要根据你使用的winit版本来调整。请参考你所使用的winit版本的文档

正确的导入可能如下：

use winit::event::MouseButton;  
use winit::event::ElementState;
