Inner panics could make it hard to trouble shoot the issues and for some
users ints not desirable.
The inner panics were left only when they are used to `assert!` during
development.
There's no need to force the static on the users, given that internally
some backends were not using static in the first place.

Lifetimes don't work nicely when dealing with multithreaded environments
in the current design of the existing winit's event handling model, so
remove it in favor of `InnerSizeWriter` fences passed to client, so they
could try to update the size.
Fixes#1387.
This renames all internal implementations of pump_events_with_timeout
to pump_events and makes them public.
Since all platforms that support pump_events support timeouts there's
no need to have a separate API.
This layers pump_events on a pump_events_with_timeout API, like we have
for Linux and Android.
This is just an internal implementation detail for now but we could
consider making pump_events_with_timeout public, or just making it so
that pump_events() takes the timeout argument.
This re-works the portable `run()` API that consumes the `EventLoop` and
runs the loop on the calling thread until the app exits.
This can be supported across _all_ platforms and compared to the
previous `run() -> !` API is now able to return a `Result` status on all
platforms except iOS and Web. Fixes: #2709
By moving away from `run() -> !` we stop calling `std::process::exit()`
internally as a means to kill the process without returning which means
it's possible to return an exit status and applications can return from
their `main()` function normally.
This also fixes Android support where an Activity runs in a thread but
we can't assume to have full ownership of the process (other services
could be running in separate threads).
Additionally all examples have generally been updated so that `main()`
returns a `Result` from `run()`
Fixes: #2709
The implementation of `pump_events` essentially works by hooking into the
`RunLoopObserver` and requesting that the app should be stopped the next time
that the `RunLoop` prepares to wait for new events.
Originally I had thought I would poke the `CFRunLoop` for the app directly and
I was originally going to implement `pump_events` based on a timeout which I'd
seen SDL doing.
I found that `[NSApp run]` wasn't actually being stopped by asking the RunLoop
to stop directly and inferred that `NSApp run` will actually catch this and
re-start the loop.
Hooking into the observer and calling `[NSApp stop]` actually seems like a
better solution that doesn't need a hacky constant timeout.
The end result is quite similar to what happens with existing apps that
call `run_return` inside an external loop and cause the loop to exit for
each iteration (that also results in the `NSApp` stopping each
iteration).
Use the definitions that `core_foundation` exposes (almost the same, except `CFRunLoopSourceContext::perform` is not nullable, so we account for that as well).
* Remove UnownedWindow::inner_rect
* Refactor custom view to use much less `unsafe`
The compiler fence is safe to get rid of now since `interpretKeyEvents` takes `&mut self`
* Refactor Window to use much less unsafe
* Refactor NSApplication usage to have much less unsafe
* Remove cocoa dependency
* Enable `deny(unsafe_op_in_unsafe_fn)` on macOS
Also re-enable clippy `let_unit_value` lint
* Remove #[macro_use] on macOS
* Refactor window delegate to use much less unsafe
* Begin abstraction over AppKit
* Clean up NSApplication delegate declaration
* Clean up NSApplication override declaration
* Clean up NSWindow delegate declaration
* Clean up NSWindow override declaration
* Clean up NSView delegate declaration
This should force the use of system libraries for Fontconfig
and freetype instead of building them with cmake if missing.
This also fixes compilation failures on nightly.
Fixes#2373.
This commit adds an `EventLoopBuilder` struct to simplify event loop
customization and providing options to it upon creation. It also
deprecates the use of `EventLoop::with_user_event` in favor of the same
method on new builder, and replaces old platforms specific extension
traits with the new ones on the `EventLoopBuilder`.

Certain platforms like Wayland don't have a concept of
primary Monitor in particular. To indicate that
'primary_monitor' will return 'None' as well as in cases
where the primary monitor can't be detected.

Changes from rebasing:

* macOS/iOS: Fix auto trait impls of `EventLoopProxy`
`EventLoopProxy<T>` allows sending `T` from an arbitrary thread that
owns the proxy object. Thus, if `T` is `!Send`, `EventLoopProxy<T>` must
not be allowed to leave the main thread.
`EventLoopProxy<T>` uses `std::sync::mpsc::Sender` under the hood,
meaning the `!Sync` restriction of it also applies to
`EventLoopProxy<T>`. That is, even if `T` is thread-safe, a single
`EventLoopProxy` object cannot be shared between threads.

* Organize Window functions into multiple, categorized impls
* Improve clarity of function ordering and docs in EventLoop
* Add additional numpad key mappings
Since some platforms have already used the existing `Add`, `Subtract`
and `Divide` codes to map numpad keys, the X11 and Wayland platform has
been updated to achieve parity between platforms. On macOS only the
`Subtract` numpad key had to be added.
Since the numpad key is different from the normal keys, an alternative
option would be to add new `NumpadAdd`, `NumpadSubtract` and
`NumpadDivide` actions, however I think in this case it should be fine
to map them to the same virtual key code.
* Add Numpad PageUp/Down, Home and End on Wayland
* Fix incorrect keycodes when using a non-US keyboard layout.
This commit fixes the issue described in #752, and uses the advised
method to fix it.
