Struct EventLoopBuilder 

pub struct EventLoopBuilder<T>
where
    T: 'static,
{ /* private fields */ }

Object that allows building the event loop.

This is used to make specifying options that affect the whole application easier. But note that constructing multiple event loops is not supported.

This can be created using EventLoop::new or EventLoop::with_user_event.

Implementations

impl EventLoopBuilder<()>

pub fn new() -> EventLoopBuilder<()>

👎Deprecated: use EventLoop::builder instead

Start building a new event loop.

impl<T> EventLoopBuilder<T>

pub fn build(&mut self) -> Result<EventLoop<T>, EventLoopError>

Builds a new event loop.

For cross-platform compatibility, the EventLoop must be created on the main thread, and only once per application.

Calling this function will result in display backend initialisation.

Panics

Attempting to create the event loop off the main thread will panic. This restriction isn’t strictly necessary on all platforms, but is imposed to eliminate any nasty surprises when porting to platforms that require it. EventLoopBuilderExt::any_thread functions are exposed in the relevant platform module if the target platform supports creating an event loop on any thread.

Platform-specific

• Wayland/X11: to prevent running under Wayland or X11 unset WAYLAND_DISPLAY or DISPLAY respectively when building the event loop.
• Android: must be configured with an AndroidApp from android_main() by calling .with_android_app(app) before calling .build(), otherwise it’ll panic.

Trait Implementations

impl<T> Default for EventLoopBuilder<T>

where T: Default + 'static,

fn default() -> EventLoopBuilder<T>

Returns the “default value” for a type.

impl<T> EventLoopBuilderExtMacOS for EventLoopBuilder<T>

fn with_activation_policy( &mut self, activation_policy: ActivationPolicy, ) -> &mut EventLoopBuilder<T>

Sets the activation policy for the application. If used, this will override any relevant settings provided in the package manifest. For instance, with_activation_policy(ActivationPolicy::Regular) will prevent the application from running as an “agent”, even if LSUIElement is set to true.

fn with_default_menu(&mut self, enable: bool) -> &mut EventLoopBuilder<T>

Used to control whether a default menubar menu is created.

fn with_activate_ignoring_other_apps( &mut self, ignore: bool, ) -> &mut EventLoopBuilder<T>

Used to prevent the application from automatically activating when launched if another application is already active.
