* fix #1087. the CFRunLoopTimer was never started if the user never changed the controlflow. * RedrawRequested ordering matches the new redraw api consistent asserts lots of appstate refactoring to rely less on unsafe, and hopefully make it easier to maintain * ios: dpi bugfix. inputs to setContentScaleFactor are not to be trusted as iOS uses 0.0 as a sentinel value for "default device dpi". the fix is to always go through the getter. * move touch handling onto uiview * update changelog * rustfmt weirdness * fix use option around nullable function pointers in ffi * Document why gl and metal views don't use setNeedsDisplay * change main events cleared observer priority to 0 instead of magic number log when processing non-redraw events when we expect to only be processing redraw events |

Usage
Winit is a window creation and management library. It can create windows and lets you handle events (for example: the window being resized, a key being pressed, a mouse movement, etc.) produced by window.
Winit is designed to be a low-level brick in a hierarchy of libraries. Consequently, in order to show something on the window you need to use the platform-specific getters provided by winit, or another library.
use winit::{
event::{Event, 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| {
match event {
Event::WindowEvent {
event: WindowEvent::CloseRequested,
window_id,
} if window_id == window.id() => *control_flow = ControlFlow::Exit,
_ => *control_flow = ControlFlow::Wait,
}
});
}
Winit is only officially supported on the latest stable version of the Rust compiler.
Cargo Features
Winit provides the following features, which can be enabled in your Cargo.toml
file:
serde
: Enables serialization/deserialization of certain types with Serde.
Platform-specific usage
Emscripten and WebAssembly
Building a binary will yield a .js
file. In order to use it in an HTML file, you need to:
- Put a
<canvas id="my_id"></canvas>
element somewhere. A canvas corresponds to a winit "window". - Write a Javascript code that creates a global variable named
Module
. SetModule.canvas
to the element of the<canvas>
element (in the example you would retrieve it viadocument.getElementById("my_id")
). More information here. - Make sure that you insert the
.js
file generated by Rust after theModule
variable is created.
