# Winit Scope
|
|
|
|
|
|
|
|
|
|
Winit aims to expose an interface that abstracts over window creation and input handling, and can
|
|
|
|
|
be used to create both games and applications. It supports the main graphical platforms:
|
|
|
|
|
- Desktop
|
|
|
|
|
- Windows
|
|
|
|
|
- macOS
|
|
|
|
|
- Unix
|
|
|
|
|
- via X11
|
|
|
|
|
- via Wayland
|
|
|
|
|
- Mobile
|
|
|
|
|
- iOS
|
|
|
|
|
- Android
|
|
|
|
|
- Web
|
|
|
|
|
- via WASM
|
|
|
|
|
|
|
|
|
|
Most platforms expose capabilities that cannot be meaningfully transposed onto others. Winit does not
|
|
|
|
|
aim to support every single feature of every platform, but rather to abstract over the common features
|
|
|
|
|
available everywhere. In this context, APIs exposed in winit can be split into different "support tiers":
|
|
|
|
|
|
|
|
|
|
- **Core:** Features that are essential to providing a well-formed abstraction over each platform's
|
|
|
|
|
windowing and input APIs.
|
|
|
|
|
- **Platform:** Platform-specific features that can't be meaningfully exposed through a common API and
|
|
|
|
|
cannot be implemented outside of Winit without exposing a significant amount of Winit's internals
|
|
|
|
|
or interfering with Winit's abstractions.
|
|
|
|
|
- **Usability:** Features that are not strictly essential to Winit's functionality, but provide meaningful
|
|
|
|
|
usability improvements and cannot be reasonably implemented in an external crate. These are
|
|
|
|
|
generally optional and exposed through Cargo features.
|
|
|
|
|
|
|
|
|
|
Core features are taken care of by the core Winit maintainers. Platform features are not.
|
|
|
|
|
When a platform feature is submitted, the submitter is considered the expert in the
|
|
|
|
|
feature and may be asked to support the feature should it break in the future.
|
|
|
|
|
|
|
|
|
|
Winit ***does not*** directly expose functionality for drawing inside windows or creating native
|
|
|
|
|
menus, but ***does*** commit to providing APIs that higher-level crates can use to implement that
|
|
|
|
|
functionality.
|
|
|
|
|
|
|
|
|
|
## `1.0` and stability
|
|
|
|
|
|
|
|
|
|
When all core features are implemented to the satisfaction of the Winit maintainers, Winit 1.0 will
|
|
|
|
|
be released and the library will enter maintenance mode. For the most part, new core features will not
|
|
|
|
|
be added past this point. New platform features may be accepted and exposed through point releases.
|
|
|
|
|
|
|
|
|
|
### Tier upgrades
|
|
|
|
|
Some platform features could in theory be exposed across multiple platforms, but have not gone
|
|
|
|
|
through the implementation work necessary to function on all platforms. When one of these features
|
|
|
|
|
gets implemented across all platforms, a PR can be opened to upgrade the feature to a core feature.
|
|
|
|
|
If that gets accepted, the platform-specific functions gets deprecated and become permanently
|
|
|
|
|
exposed through the core, cross-platform API.

# Features

|
|
|
|
|
## Extending this section
|
|
|
|
|
|
|
|
|
|
If your PR makes notable changes to Winit's features, please update this section as follows:
|
|
|
|
|
|
|
|
|
|
- If your PR adds a new feature, add a brief description to the relevant section. If the feature is a core
|
|
|
|
|
feature, add a row to the feature matrix and describe what platforms the feature has been implemented on.
|
|
|
|
|
|
|
|
|
|
- If your PR begins a new API rework, add a row to the `Pending API Reworks` table. If the PR implements the
|
|
|
|
|
API rework on all relevant platforms, please move it to the `Completed API Reworks` table.
|
|
|
|
|
|
|
|
|
|
- If your PR implements an already-existing feature on a new platform, either mark the feature as *completed*,
|
|
|
|
|
or mark it as *mostly completed* and link to an issue describing the problems with the implementation.

## Core
|
|
|
|
|
|
|
|
|
|
### Windowing
|
|
|
|
|
- **Window initialization**: Winit allows the creation of a window
|
|
|
|
|
- **Providing pointer to init OpenGL**: Winit provides the necessary pointers to initialize a working opengl context
|
|
|
|
|
- **Providing pointer to init Vulkan**: Same as OpenGL but for Vulkan
|
|
|
|
|
- **Window decorations**: The windows created by winit are properly decorated, and the decorations can
|
|
|
|
|
be deactivated
|
|
|
|
|
- **Window decorations toggle**: Decorations can be turned on or off after window creation
|
|
|
|
|
- **Window resizing**: The windows created by winit can be resized and generate the appropriate events
|
|
|
|
|
when they are. The application can precisely control its window size if desired.
|
|
|
|
|
- **Window resize increments**: When the window gets resized, the application can choose to snap the window's
|
|
|
|
|
size to specific values.
|
|
|
|
|
- **Window transparency**: Winit allows the creation of windows with a transparent background.
|
|
|
|
|
- **Window maximization**: The windows created by winit can be maximized upon creation.
|
|
|
|
|
- **Window maximization toggle**: The windows created by winit can be maximized and unmaximized after
|
|
|
|
|
creation.
|
2019-12-22 17:04:11 +11:00
|
|

|
|
|
